A supernova (pl. supernovae ) is a stellar explosion. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over s...

The supernova, known as SN 2007on, was identified as a Type Ia supernova. Astronomers generally agree that Type Ia supernovas are produced by the explosion of a white dwarf star in a binary star system. However, ... "Finding the progenitor to one of these Type Ia supernovas is a great chase in astronomy right now," he said.

If this is the case, strong winds from the mass-accreting white dwarf change the stability condition up to q , 1.15 and are able to open a channel to a Type Ia supernova explosion. 2.

Supernova Legacy Survey Finds a Superbright, Supermassive Type Ia Supernova in a Young Galaxy ... But how could a carbon-oxygen progenitor ever accumulate mass greater than the Chandrasekhar limit without exploding? It's possible that a very rapidly spinning star could be more massive. It's also possible that two white...

Hubble Space Telescope (HST) WFPC2 archival F606W and F300W images obtained within 1 year prior to the explosion of the nearby Type II supernova (SN) 2003gd in M74 (=NGC 628) have been analyzed to isolate the progenitor star.

The immediate progenitor of a Type I supernova (SN I) is thought to be a mass-accreting carbon−oxygen (C−O) white dwarf in a binary system.
