question 12
what occurs when a white dwarf in a binary star system if it gains mass beyond the chandrasekhar limit?
type i supernova
type ii supernova
red dwarf formation
black hole formation
neutron star formation

Explanation:

A white dwarf in a binary system that accretes mass beyond the Chandrasekhar limit (about 1.4 solar masses) undergoes a runaway nuclear fusion reaction. This leads to a Type I Supernova. Type II Supernovae occur from the core - collapse of a massive star (not a white dwarf). Red Dwarfs are low - mass stars, and their formation is not related to a white dwarf exceeding the Chandrasekhar limit. Black Hole and Neutron Star formations are associated with the core - collapse of very massive stars (for black holes, even more massive than those that form neutron stars), not with white dwarfs in binary systems exceeding the Chandrasekhar limit.

Answer:

Type I Supernova
