Interesting Planet Apparently Heating Its Star
T. Panimaesh writes "A Canadian graduate student has discovered a planet which is heating the star it rotates around. 'Evgenya Shkolnik detected a spot on HD179949 that was 700 degrees warmer than the surrounding areas and circled the star at the same pace as the planet's orbit, once every three days. First seen in 2001, it also appeared in two sets of observations in 2002. It is probably not an intrinsic feature of the star, which takes nine days to rotate. Instead, the planet appears to possess a magnetic field that interacts with the star's magnetic field.' The 'roaster' planet being studied is almost as big as Jupiter, a gas giant planet in our solar system, and has 270 times the mass of Earth. It moves at 150 Kilometres per second, completing it's orbit in just 3.5 days."
Could anyone post the contents of the article "just in case it's slashdotted"?
Thanks
If ANYBODY here did not know that... well, kill yourself. You have no right to be anywhere near a computer, let alone a "News for Nerds" site.

Here, doggy, doggy!
It's not, so where are the pictures? :-P
A hacker from Canada has been wardriving in said area and reported that the star's hotspot is IEEE 802.11 compliant.
I wonder what use it would be with a 176yr ping time! DOH!

Well, just your basic law of averages. Most of the planets we've been able to find have been much larger than Jupiter. We've only recently been able to detect Jupiter-size planets.
It's not a difficult extrapolation.

Is anyone else thinking that this gas giant houses a hyper intelligent race of celestial beings? Perhaps there is a satellite array which mantains the strange orbit and prevents the large planet from colliding with the star and destroying the system. Perhaps this array has an advanced energy system which creates the heat bursts we have detected!! AHA!!! Perhaps!!!

Obviously, you aren't an Earthlink user.
TOS: A scientist (who lives alone except for his beautiful daughter) is conducting dangerous energy experiments.
TNG: Don't worry, it will be figured out in the last 15 minutes. Data and Geordi right now are trying to trace the source of unknown photocron emissions that were detected at the beginning of the episode.
DS9: You already mentioned the race of celestial beings.
Voyager: Whoever it is, I wonder if they want to eat some of Neelix's leftover burnt Antarean alpha-truffles
Enterprise: It's gotta be the Xindi.
Don't blame Durga. I voted for Centauri.
Yet, you have to admit that the show had too many of the "Data and Geordi try to figure out strange particles/emissions/transmissions/apparitions" type.

Most likely, either tidal or mag.field effects are changing the convection patterns inside the star. All stars are _much_ hotter in the core than on the surface, it wouldn't take much to influence these boundary-condition dependant internal convective flows.
Woah, back up there. This 'Jupiter' you speak of, it's a what, now? A planet, here in our solar system? Wow! Please, tell me more!

Is it really necessary to tell us that Jupiter is a planet in our own solar system? I'm not from the USA , but I assume your educational system isn't that bad!
Why is anything anything?
A year on Mercury takes 87.97 Earth days; it takes 87.97 Earth days for Mercury to orbit the sun once.
Logicly the planet must be closer much closer than Mercury is to our Sun. I could just be a phenomenon similar to the tides caused by the moon.
Obviously it's completely populated by women and with no one to stop them they keep cranking the thermostat up...
There was a NYT article yesterday about how the US National Park Service is "re-evaluating" plaques that it placed in the Grand Canyon expressing the theory that the canyon was created during the Biblical Flood and is only a few thousand years old. Apparently the Bush Administration wants the plaques to be kept in the park, and other (read "sane") people are shocked and awed by the ignorance involved. If a number of US citizens REALLY believe that the Grand Canyon was formed when Noah was on an ark, then there is no logical limit to their ignorance. It may be hard to understand if you don't live here, but the scientific method is no longer taught in public schools. The idea of subjecting a hypothesis to tests conflicts with the value of "faith-based education" which gives us more in common with Iran than anywhere else. Oh well, I guess we'll always need gas station attendents. They can believe that the Grand Canyon came from the tears of Quarnog the World Unicorn if it makes them happy.
Most of the planets we've discovered outside our solar system are gas giants orbiting very close to their parent stars. Is there any theories to how these planets formed? I remember reading somewhere that the gas giants formed in our solar system because they were so FAR away from the sun (something to do with ice crystals, and how they weren't vaporized becuase they were so far away from the sun). So how is it that gas giants in another solar system can be so close? And really close, I mean - the article says this planet is only 4 million miles away from the sun. I'd like to know how stable this solar system is, and if it will rip itself apart in a few thousand years.

...and if it's interacting with the star at all, then the changes must be dragging energy out of the planet, ergo, the planet's orbit will decay and probably swiftly. Magnetism is going to be a huge effect if the range is short enough for a 3.5-day orbit. Think dynamo. Think closer, and faster.

I'm a white man. I'd like to ask you to suck my cock. Unless your a man, then I'd ask you to go fuck yourself. On the freeway, in the middle of the night.
Thanks.
No.
...then you'll be several orders of magnitude out in your forces. If you run into a "squared" or similar factor anywhere in your terms, the butterfly can suddenly morph to StarGlider size.

This planet is 270 times the mass of Earth, or 1.6x10^27 kg.
The velocity of the planet is 150 km/sec.
Kinetic energy = 1/2 * mass * velocity^2.
This planet's kenetic energy = 1.82*10^37 kg(m/sec)^2.
E=mc^2.
1.82*10^37 kg * (m/sec)^2 = mc^2.
1.82*10^37 kg * (m/sec)^2 = m(3*10^8)^2.
The kinetic energy of this planet is equal to 2^20 kg of pure mass.
The entire energy output of our sun is 1.4 * 10^17 kg per year.
You could take our sun and mount it as a (perfect efficency) rocket engine on this planet and it would still take nearly 1,500 years to kill its orbital momentum.
That is what I meant when I said "Any planet (expecially a Jovian) will have a monsterously large amount of inertial energy in its orbit."
Any attempt to pour the entire energy output of our sun into a planet would obviously vaporize it almost immediately. The order of magnitue is so monsterously large that any force attempting to do so in less than geological time scales would vaporize the planet first.

...and awed at the effort you put in against my simple answer. I wasn't thinking of slowing it rocket-style but using magnetic braking. If it had been so braked, one would expect the planet's spin to be magnetically "tide locked" to the primary (like our own Moon) to a much greater extent than could be explained by gravity alone, and one would expect heating of the primary side of the planet in considerably greater degree than could be explained by radiation. I wonder if doppler on the limbs of the planet and/or the planet's spectrum as a whole would be accurate enough to tell us anything about that.
I would like to try taking lots of spectra at fixed intervals and looking for a wavy set of hot-but-not-stellar hydrogen lines alongside the star's more-or-less invariant stellar hydrogen.

Aaron Dragushan's relationship with that Evganja chick is just a front to hide his gay love affair with that liberal moron Adrian / DJ Mischiff.
