Hubble Captures a Protoplanetary Disk

Astroturtle writes "The Hubble Space Telescope's new Advanced Camera for Surveys (ACS) has captured a detailed image of spiral rings in a distant protoplanetary disk -- the pancake-shaped cloud of gas and dust around a young star in which planets are expected to condense. But contrary to earlier suggestions, the intricate structure of this particular disk is probably caused by a nearby companion star rather than by embedded planets starting to form."

Makes one wonder

[zokum]

Every time something like this is published, makes me wonder when we'll discover extra-terrestrial life. I honestly don't think it's a question of if, it's more about what, and whether they still are around. Seti@home might not be the solution, but as with all science, one has to start somewhere :-)

Re:Makes one wonder

[WegianWarrior]

It seems such a waste of space if we're alone... even more so if you're semi-religious as I am (I believe that science can explain most of the universe around us, but it was probaly the "great arcitect" that set it up to begin with). As we learn more about the universe and life, we may understand where and how to look for life out there.

Life is one thing, intelligence is different. Before we all get worked up over SETI@home, why not take a look at STI@home - the search for terrestial intelligence?

Did anyone besides me see the story title and think: Wow, straight out of Ghostbusters!

I think the best place to look for life "out there" is wherever there's dryers that eat socks, because that's a sure sign of intelligent life.

I hold a similar semi-religious viewpoint, but sometimes my views are more along the lines of... God == Universe. Makes religious ideas different in interesting ways...

Re:Makes one wonder

[Bicoid]

Whether we'll find extraterrestrial life (self-replicating microenvironments that maintain homeostasis) is a given. Whether we'll recognize it as such is something completely different.

And on the briht side, when we finally have the technology to get to this star system, the planets will already have coalesced and enough time will have passed for life to develop (possibly more than enough time if NASA keeps up their present track record).

Re:Makes one wonder

Not hard to find the Satanic elements of Catholicism, they are quite clearly evident. From the bent crucifix to the "vicar" (look up "vicar" and you'll see why that's so evil)of Christ claim by the Pope, prayers to the dead, worship of Mary, worship of idols, Satanic elements abound in Catholicism.

As to the elements of Masonry, again in their own words (from people like Christopher Pike, the father of US Masonry):

"To the crowd we must say: we worship a God, but it is the God one adores without superstition. To you Sovereign Grand Inspectors General, we say this, that you may repeat it to the Bretheren of the 32nd, 31st and 30th degrees: all of us initiates of the high degrees should maintain the Masonic religion in the purity of the Luciferian doctrine... Yes, Lucifer is God, and, unfortunately Adonay is also God... religious philosophy in its purity and truth consists in the belief in Lucifer, the equal of Adonay."

Jupiter and/or Saturn

[The Ape With No Name]

Help me with my astronomy! Can we infer that the Gas giants might have helped form the inner planets if a companion mass like a star or large planet is necessary to do so? I don't know the accepted timeline/sequence of planetary formation in our system, but this kinda popped to mind.

Re:Jupiter and/or Saturn

[Anonymous Coward]

The lighter gasses are pushed to the outer reaches of the star system. These then go on to form the gas giants. Heavier materials such as iron and silicates condense inwards and form the smaller rocky, "terrestrial" planets. Hence the pattern in our system of four small rocky worlds in the inner area and gas giants making up the more distant rest.

Re:Jupiter and/or Saturn

[zer0vector]

I'm having a little trouble understanding your question, but I think what you're asking is "Would a massive companion body, be it a star or planet, aid in the formation of inner planets?" The answer to that is: kind of. They don't necessarily aid in the formation, but a large body would have the tendency to deflect smaller bodies, thus clearing the areas close to the star of debris. In our case this obviously helped with the formation of life. If the geometry or timeline changed a bit, however, it can be easy to see how a massive companion could inhibit the formation of smaller bodies. Assuming Jupiter was a bit closer to the sun, and was around before any largish planetesimals formed, it's gravity would tend to disperse the planet-forming materials, and lead to a system without close-in rocky planets. So it could really go either way, depending on the timeline you choose.

Re:Jupiter and/or Saturn

[CheshireCatCO]

Sorry, but not right. The proto-solar nebula was probably pretty well-mixed in elemental abundances. The reason you get rocky/metallic planets in close and icey giant planets further out is purely a matter of temperature. The inner disk is much hotter than the other disk, so that hydrogen compounds like methane, water and ammonia cannot condense into solid forms. Since there are 10 times as much of these compounds as metals and silicates, planets forming father out (past the "frost line" where water first can freeze out) have much more material to build with. Thus this build faster and into more massive bodies. At around 10 Earth-masses, the cores can start to hang on to nebular gasses like hydrogen and helium. And you get a giant planet. Inside the frost line, you're struck building with rocks and metals, and you get a smaller planet.

No pushing or pulling of specific elements/compounds is involved.

Re:Jupiter and/or Saturn

[CheshireCatCO]

Actually, you can infer that. (Although I don't see it coming from this bit of research.) Simulations indicate that having a Jupiter-ish planet in place helps the formation of the inner solar system along. But, of course, simulations are only so accurate.

Re:Jupiter and/or Saturn

[rajohn]

Nicely done. You are quite right, temperature, plus angular momentum, have more to do with it (planetary formation) than does mass. Without the initial rotation, there most likely would be no planets at all, all material having fallen down to the center in the early collapse!

Spiral form

[MonkeyBoyo]

the intricate structure of this particular disk is probably caused by a nearby companion star rather than by embedded planets starting to form.

I thought that standard opinion on spiral forms (e.g. galaxies) was that they were created by interaction with massive companions.

Who has ever proposed that internal bodies can cause a spiral form?

Re:Spiral form

[Doctor Fishboy]

I thought that standard opinion on spiral forms (e.g. galaxies) was that they were created by interaction with massive companions.

Spirals in galaxies and these spirals in protoplanetary disks have different origins, and in the galactic spirals case, you don't need a binary companion to cause spiral structure.

Who has ever proposed that internal bodies can cause a spiral form?

OK, this is probably a gross simplification, so if there are any disk formation astronomers out there (you know who you are!), they'll give a much better description than this one!

It partially depends on the viscosity of the material in the disk, and where most of the mass resides. If the mass of the disk is much smaller than the mass of the central star, the disk structure is dominated by the gravitational field of the central star and this tends to smooth out any spiral structure in the disk, and then you need a binary companion to stir up spiral modes in the disk.

If the disk itself is massive enough, and the viscocity of the material is low enough, the disk's gravitational field can amplify up any spiral patterns that occasionally appear. So no, you don't need a binary compantion if the disk is massive enough. In this specific case, though, the disk mass is small, and so there's probably a binary companion acting as a swizzle stick.

For galaxies, nearly all the mass resides in the disk of the galaxy and not in the centre (the mass of the black hole in the centre of the galaxy is tiny compared to the rest of the mass in our galaxy, and there's a honking huge halo of dark matter, I know, I know...) and so spiral modes tend to be self-reinforcing as they sweep around the galaxy.

Blurgh, too early on Saturday morning...

Dr Fish

Re:Spiral form

[MonkeyBoyo]

If the disk itself is massive enough, and the viscocity of the material is low enough, the disk's gravitational field can amplify up any spiral patterns that occasionally appear.

Do you have any references? I'm pretty sure I've read about simulations that show that spirals don't evolve from nothing. And simulations showing how interaction with other galaxies can cause spirals.

If spirals can occur in a vacuume then why have the overwhelming number of galaxies which are elliptical not become spiral yet?

Re:Spiral form

[Doctor Fishboy]

I think we may be both right, according to this reply on the Cornell ask an astronomer site, the 'self peturbation' theory can explain the fuzzier spiral arm galaxies, but not the larger grand design galaxies, which do need an external companion. It's not clear cut at all, though.

As for your second question, it's to do with the way the stars orbit in a galaxy. If you could draw all the orbits of the stars in a spiral galaxy, you would see a badly stacked set of hula-hoops, - most orbits are nearly circular, and they all go around the galaxy in the same direction. With an elliptical galaxy, the orbits would resemble a tangled hairnet. There's no perferred axis of rotation, and there are many very eccentric orbits.

You tend to see giant elliptical galaxies sitting in the middle of groups of smaller spiral galaxies, and it is thought that collisions between spiral galaxies lead to formation of giant elliptical galaxies. The interaction of the two spiral galaxies' gravitational potentials then scrambled the orbits of the stars together.

Spiral structure NEEDS ordered co-rotating material in which to form, so that's why ellipticals don't form them -the orbits of the stars are too randomised to form them.

I hope this makes some sense!

Dr Fish

I wouldn't say spectacular, but the photos are impressive for the detail available. (I'm spoiled from all the color nebula shots.) The spiral formations are easily visible, even without the 'cheatsheet' image.

Shame the images can't capture all the close-in dust. Considering that Pluto's only 40 a.u. out, having data from almost 100 a.u. around the star missing means a lot of the prime planetary formation area isn't available to examine.

Then everyone who read the first report and misses the revision can walk around being stupid by knowing false information.

It's brightness seen from Earth (presumably) is about a factor of two fainter than the faintest star you can see on a clear, dark night.

Re:It's all Greek...

[reverseengineer]

Just adding to that excellent explanation, the arcane code HD 141569A merely gives the star's listing in the Henry Draper Catalogue, a gigantic star catalogue (over 250,000 entries) first compiled about a century ago. The spectral class A does denote that HD 141569A is a young, fairly massive, and hot star- its surface temperature should be between 7,500 - 10,000K, and it should be white to blue-white in color. Another example of an A type star would be Sirius.

I also wanted to point out that the story submitter gets it a bit wrong- which is more the fault of the story, which fails to make this clear- HD 141569A is not in a binary system with a single companion star, it is in a three star system with two other stars. These other two stars, HD 141569B and HD 141569C, are in a binary relationship with each other, and together perturb the disk around HD 141569A, which is over 100 billion miles from the pair. This paper (.pdf file) from 1999 on the Arxiv gives more details on the star system and protoplanetary disk.

actually, as a Californian, I'll tell you exactly what happened with the power comapnies: The back-end suppliers were de-regulated without removing the rate caps from the market-end. The result was definately NOT privatized electricity, and absolutely doomed to fail whether it was constructed in a communist or capitalist environment. The idea of having every company owned and run by the government (pure communism) is just as bad as the idea that government should have no power to break monopolies (pure laissez faire capitalism). In both cases, power accumulates to an unacceptable degree within the hands of too few people. Examples: Soviet Russia. Sorry to break the news, but it fell. Another example: Debeers. Diamonds are practically worthless. The only reason they get such a high asking price is that one company controls over 90% of the world's supply and they can keep it lower than demand. It's the same game OPEC plays.

Progressivism is definately the wrong term for a theory that demands cradle-to-grave governmental hand-holding. It's not forward thinking. It's simply restoring the monarchial powers of state without simply giving the throne to a single family. It is just as conservative wanting the government to step aside and allow the establishment of a corporate fiefdom.

Make you think..

I know the planet in the picture isnt far enough away in this case, but it would be great if hubble showed us a picture of a proto-planet/star/galaxy a few million light years away, why by now, has become an earth like planet, with an advanced civilisation that has discovered FTL travel, who are now on their merry way to earth to say hi! (Or less great - with big guns aimed in our direction).

sorry but i still disagree. I think Ross Perot and his buddies know more about the energy monopoly crisis than you or me.

Please don't compare Russian ruled markets to our Military or Utilities. If they were in private hands we would be screwed big time because market forces can't apply . How many companies out there build nuclear submarines?

The diamond example you mention is weak for this reason, diamonds are rocks , yeah ,you're right, but digging them up out deep in the ground is not easy and costs money. Tools and labor your not mentioning.

You can only have fair,free markets if there are enough players. Not enough then you have market collusion. Wouldn't it be better to have the gov monitor important sectors that don't have competition and can regulate prices openly.

I got to tell you that i had up to here with the broadband/monopoly networks of this country. They stink. They're private enterprise and they suck. If the government ran them we would be paying only 1/3 the price.

They would probably turn the question around

You're just being paranoid and weird." I happen to agree with you that cookies should not be required except when used for actual functionality (banking, shopping, email online). This is obviously not one of those cases. My only point is that _they_ don't see the problem with cookies in the first place because they don't think like us. They probably bought every version of Windows when it came out, and they probably think DRM is good for artists and users. A friend said something last night that first this perfectly: "I don't understand why people insist on being wrong."

Naw....

The proof, that there is intelligent life out there is....
They DON'T come and visit us....
What would THEY do with us anyway??

Of course! We all know that downloading copyrighted material (pictures, no less) from the Internet is a terrorist activity, right?

Anyone noticed?
