Two Totally Unique Star Systems Discovered

[Science News]

esocid writes "Astronomers have spied a faraway star system that is so unusual, it was one of a kind — until its discovery helped them pinpoint a second one that was much closer to home. In a paper published in a recent issue of the Astrophysical Journal Letters, Ohio State University astronomers and their colleagues suggest that these star systems are the progenitors of a rare type of supernova. In research funded by the National Science Foundation, they found a star system that is unusual, because it's what the astronomers have called a 'yellow supergiant eclipsing binary' — it contains two very bright, massive yellow stars that are very closely orbiting each other. In fact, the stars are so close together that a large amount of stellar material is shared between them, so that the shape of the system resembles a peanut."Read more of this story (http://science.slashdot.org/article.pl?sid=08/04/01/0727249&from=rss) at Slashdot.
