Question : 45 [SSC SO 2005]
What is supernova ?
a) A dying star
b) A comet
c) An asteroid
d) A black hole
Answer »Answer: (a)
The Supernova is a stellar explosion that is more energetic than a nova. The explosion expels much or all of a star’s material. Supernovae can be triggered in one of two ways: by the sudden re-ignition of nuclear fusion in a degenerate star; or by the collapse of the core of a massive star. The core of an ageing massive star may undergo sudden gravitational collapse, releasing gravitational potential energy that can create a supernova explosion.
Alternatively, a white dwarf star may accumulate sufficient material from a stellar companion (either through accretion or via a merger) to raise its core temperature enough to ignite carbon fusion, at which point it undergoes runaway nuclear fusion, completely disrupting it.
