The X-ray emissions follow the visible explosion occurring when a white dwarf star nears the end of its life. "These novae are a new class. They would have been overlooked before," said Wolfgang Pietsch of the Planck Institut. Previous surveys only examined regions about twice a year, giving time for fast X-ray novas to come and go without being seen. The fastest changing novas are thought to be associated with the most massive white dwarfs. Pietsch's team have been allocated additional XMM-Newton and Chandra time, and plan to observe novas in Andromeda at ten-day intervals for several months beginning in November.{moscomment} |
