Star Destroyed Supernova Was White Dwarf bi13251817 Based on the brightness of the explosion, occurred 21 million light-years away the Pinwheel Galaxy (M101), and the fact that the explosive debris contained large amounts of carbon and oxygen, coauthor Peter Nugent of LBNL and colleagues concluded that before exploded, the star was almost certainly a carbon-oxygen dwarf

Mystery of 400-Year-Old Star Explosion Finally Solved bi13251817 Call a cosmic scene investigation. A team of astronomer sleuths has identified the trigger for a powerful supernova that exploded four centuries ago, finding to be the collision of two dwarf stars

Earliest-yet observation of August supernova nails it: Destroyed star was whi bi13251817 ( University of California - Berkeley ) The supernova SN2011fe, first noticed August 2011 a mere 11 hours after exploded, was the closest Type Ia supernova decades and allowed astronomers to narrow down the identity of the progenitor star to something the dwarf range. A chance observation only four hours after the explosion has now let UC Berkeley astronomers put even stronger ..

Supernova traced to collision of white dwarf stars bi13251817 Two scientists studying a Type 1a supernova may have pinned down the cause of such massive stellar explosions, they report the journal Nature. Type 1a supernovae, exploding stars that can outshine entire galaxies, were instrumental to the Nobel Prize-winning discovery that a mysterious "dark energy" fueling the expansion of the universe. But astronomers haven't been able to pin down what ..

August Supernova Was A White Dwarf bi13251817 Fluke observation 4 hours after star exploded allows stronger limits on size of progenitor Last year's discovery of the nearest Type Ia supernova decades ? captured only 11 hours after exploded ? allowed astronomers to finally cinch the identity of the stars behind these explosions, have become key measures of cosmic distance. That supernova, called SN2011fe, and presumably most Type ..
