View Full Version : New Method for Finding Exploding White Dwarf Stars

SUMMARY: Researchers at the University of Washington have developed a new method for studying unusual astronomical pairings: pre-cataclysmic variables - a white dwarf and red dwarf tightly orbiting one another. Before this new method, only 100 of these objects had been discovered, but this new method has turned up another 400 in data from the Sloan Digital Sky Survey. When the two stars get close enough, material from the red dwarf streams onto the white dwarf and deposits on the surface. This heats up the white dwarf and can cause it to explode as a supernova.
