NASA's Hubble Space Telescope has identified a star a million times brighter than the sun that exploded as a supernova in 2005 — well before it should have, according to current theories of stellar evolution. The doomed star, estimated at about 100 times our sun's mass, was not mature enough, according to theory, to have evolved [...]

How solid is that identification of the progenitor star?

Fraser. Happy 10th birthday. They really need work on supes. see:http://arxiv.org/PS_cache/arxiv/pdf/0903/0903.3378v1.pdf

like the author, Panagia, I too have been studying supernova since ~ 1978, and have pointed out the need for including rotation, and magnetic field effects, since April of 1982.(first paper). pete
