KentuckyFC writes "It doesn't happen very often but astronomers have discovered a new class of pulsating white dwarf. The work began last year when the Sloan Digital Sky Survey found a few exotic white dwarf stars with carbon atmospheres. A mathematical model of these stars showed that in some circumstances the dwarfs could pulsate as the carbon was cycled through the atmosphere by convection. Now a few days observation of one of these stars has shown that it does actually pulsate as predicted."Read more of this story (http://science.slashdot.org/article.pl?sid=08/03/21/1639238&from=rss) at Slashdot.
