Newly Discovered Star Has an Almost Pure Oxygen Atmosphere (popularmechanics.com)
William Herkewitz, reports for Popular Mechanics: A newly discovered star is unlike any ever found. With an outermost layer of 99.9 percent pure oxygen, its atmosphere is the most oxygen-rich in the known universe. Heck, it makes Earth's meager 21 percent look downright suffocating. The strange stellar oddity is a radically new type of white dwarf star, and was discovered by a team of Brazilian astronomers led by Kepler de Souza Oliveira at the Federal University of Rio Grande do Sul in Brazil. The star is unique in the known pool of 32,000 white dwarf stars, and is the only known star of any kind with an almost pure oxygen atmosphere. The new white dwarf has a mouthful of a name -- SDSSJ124043.01+671034.68 -- but has been nicknamed 'Dox' (pronounced Dee-Awks) by Kepler's team. The discovery was reported today in a paper in the journal Science.
No smoking on that planet...
If you want news from today, you have to come back tomorrow.
Who the hell thought this "slashvertisement" thing would be funny?
No worries - he'll only visit at night (cue sad trombone noise...)
Quo usque tandem abutere, Nimbus, patientia nostra?
I wouldn't buy it. It is in a bad neighborhood. Neighbors regularly have supernova parties.
It's a real article, as are all the others on the front page. Get your panties out of a bunch. What do need to stop doing exactly? Posting articles on April 1?
Apparently (and I get this from reading the article), it's not just the surface that's 99% oxygen, it's the whole star that is mainly oxygen.
Also the crazy thing is how he found it.......he had data from 300,000 stars printed out, on 300,000 pages, and just started reading through them one by one to see if there was anything interesting in the data.
"First they came for the slanderers and i said nothing."
That's the Brazilian way to make science. By the way, Kepler de Souza Oliveira sounds like a very appropriate name for a Brazilian astronomer.
Linux is for people who don't mind RTFM.
Ok see ya
Now that's what I like to see. I seem to recall that my very first post to you, on your very first day, was mentioning the need to say things pretty much just like that.
You can't please 'em all and it's futile to try. There is, literally, not one thing you can do that will make everyone happy. Sometimes, you just gotta tell 'em to pound sand. Which, well, you just did.
I, for one, appreciate our new realistic and mostly down-to-Earth overlords. I also second your sentiment but I do worry that we're having a bad influence on you. ;-)
"You were such a nice young man, until you started hanging around *that* crowd." Say the old ladies who amass around the village well. "Well, I'll never let MY daughter anywhere near him." Exclaims one of them, as the rest titter and nod in affirmation.
"So long and thanks for all the fish."
But the patterns aren't random. Most stars spectra will will fall into one of a handful of standard classifications, and all those should be immediately removed from the potential "interesting" set as they are only relevant for determining the standard deviation within their cluster for purposes of deciding just how strange other stars are.
If you're specifically looking for interesting compositions, you could do things like categorizing the dominant elements in a star based upon it's emission lines, and then look for anything with an abnormal composition. This isn't rocket surgery, I've got little background in data analysis, and even I can feel the shape of the software I'd need to write to find odd-composition stars, might take me an afternoon or two without using any special tools. And that's before even considering things like the the mathematical packages designed specifically to perform clustering of N-dimensional data sets.
Now granted, there's still a lot of weirdness a human might spot that I wouldn't know how to begin to program for, but an oxygen star? That should have been flagged as unusual within minutes of recording its spectrum.
