Astronomers Have Found the 1st Star with an Almost Pure Oxygen- Atmosphere

According to current findings reported in Journal Science, astronomers have exposed a new type of star that up until this point had only been exist theoretically. An very old sun that has survived over the period of time so long, that its furthest layer is now composed almost totally of pure oxygen. When stars, with less than ten times the mass of our Sun, come close to finish of their lifespan, they lose their outer layers and turn into what are called white dwarfs. Under strong gravity, the heaviest elements incline into the star's thick core, while lighter elements for instance hydrogen and helium rise to the outside. That what’s happen according to our present knowledge.
 But this newly discovered star, called SDSS J124043.01+671034.68, doesn’t follow this trend, with astronomers notice that its outer atmosphere is basically greater than 99.99 percent oxygen. Only traces of other elements have been recognized, comprising neon, magnesium, and silicon, but as for the hydrogen & helium you'd suppose to find scheming the surface, there's no sign.
It's an enigma for the group of astronomers that exposed it, led by Souza Oliveira Kepler from the Federal college of Rio Grande do Sul in Brazil. He told William Herkewitz at Popular Mechanics "What happened to all these glow elements? How did they all get stripped gone?"
Astronomers have long careful that elements being stripped from a star's exterior over time could be a possibility. If that's exactly what's took place here, SDSS J124043.01+671034.68 (or 'Dox' as the scientists have nicknamed it) is the first indication of the phenomenon taking place. Except how did the other elements get stripped away? Nobody knows for sure.

This oxygen-dominated star is a right one-of-a-kind in terms of the solar bodies we at present know about, life form the only star amid some 32,000 white dwarfs with such a perfect oxygen atmosphere.
