In the past decade, robotic telescopes have turned astronomers' attention to strange exploding stars that may point to new and unusual physics. An international team of astronomers has uncovered a supernova whose origin cannot be explained by any previously known mechanism and which promises exciting new insights into stellar explosions.
SN2005E was first spotted on January 13, 2005 in the nearby galaxy NGC1032. Since then, scientists have carried out various observations of it using different telescopes including the Keck, the world's largest, at Mauna Kea, Hawaii. Analysis of the collected data, theoretical modeling and interpretation led to the conclusion that SN2005E wasn't a typical supernova.
Supernovae result from the collapse of very massive stars or by thermonuclear detonation on the surface of white dwarf stars composed mainly of carbon and oxygen.
"But this one, although it appears to be from a white dwarf system, is devoid of carbon and oxygen. Instead it's rich in helium. It's surprisingly different," said Dae-Sik Moon of the University of Toronto's Department of Astronomy & Astrophysics.
