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.

Burning (aka fire) is a chemical reaction, and suns are typically much too hot for any stable chemical bonds to exist for fire to rearrange. In fact I would guess that the plasma is so ionized that the nuclei don't even have any bonded electrons with which they could engage in any chemical reaction at all, no matter how fleeting.

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.

Since you're referencing the H-R diagram, I suspect you mean that it can be between 10^-5 and 10^0 of the luminosity of the Sun, but not necessarily the size (in terms of metres). Luminosity is related to the size (by a squared relationship) and the temperature (by a quartic relationship, or is it quintic?). You're OK on the temperature, which in itself gives up to a 625 (or 3125, if it's quintic) fold luminosity range. Owwww. Not wrong ... but a really, really coarse introduction to spectroscopy.

      Also the crazy thing is how he found it.......he had data from 300,000 stars printed out, on 300,000 pages,

      In TFP, the only mention of data set size is that there were 4.5 million spectra taken in the Sloan Digital Sky Survey (the SDSS part of the object's name, not in the least bit mysterious), but no mention of how they selected this particular star. Almost certainly, they had grounds not described in TFP, but in TF-Supporting Online Material, but I don't have access to that. However, TFA in Science does say that they examined around 32,000 spectra (and doesn't mention their methods.

      I'd check the derivation of the 300,000 print outs story before repeating it. If you've got any attachment to accuracy, that is. Personally, I don't think it's either credible - that's over 1.5 tonnes and several week's wages of paper alone. Let alone the problems of actually maintaining order over these things. 32000 printouts is pretty incredible too (but I don't make that claim).

      it's not just the surface that's 99% oxygen, it's the whole star that is mainly oxygen.

      Again, TFP doesn't say that. Specifically, they point out the presence of around one part of silicon in 3200 of oxygen, and one part of calcium in >316000 of oxygen. They suggest that this may indicate oxygen burning (16-O + 16-O --> 28-Si + 4-He) in the progenitor star and a trace of silicon burning (28-Si + 4-He + 4-He + 4-He --> 40-Ca).

      While atmosphere isn't the most accurate way of describing the outer layers of a star, it seems reasonable to use it when describing the phenomena of a stars outer layers to laymen.

      Perhaps your education didn't teach you that oxygen comes after helium and before neon in the layers of a large star, which of course leads to the possibility of the outer layers getting blown off, leaving a star with an oxygen outer layer?

Photosphere, etc., do not consist of pure oxygen. To read a story like that on the first of April does not add any certainty that this makes any sense, most likely a hoax.
