That is one of the standard candles - type 2 supernova IIRC - when neutron star in binary system is eating the other star and turns nova very predictably.

- larubbio 13y agoI think it's type 1a. There was a discussion on this recently after a new supernova observation. https://news.ycombinator.com/item?id=7104056 https://news.ycombinator.com/item?id=7104056 Basically it's unknown if it is a two star system where the neutron consumes the partner, or a three star system where two neutron stars collide head on.
- splat 13y agoThe standard candles are Type Ia supernova which are when white dwarfs exceed the Chandrasekhar mass and become neutron stars. It is thought that when neutron stars exceed the maximum mass of a neutron star (which is not well known, by the way) they form a gamma-ray burst.

It's when the star's gravitational pressure exceeds neutron degeneracy pressure and collapses into a black hole. http://en.wikipedia.org/wiki/Tolman–Oppenheimer–Volkoff_limit http://en.wikipedia.org/wiki/Tolman–Oppenheimer–Volkoff_limi...
