Question

Quizplus · Accepted Answer

A nova is most likely to occur in a binary system containing a white dwarf with a mass considerably below the Chandrasekhar limit (1.4 solar masses). In such systems, material from a companion star can accumulate on the white dwarf's surface until it undergoes a thermonuclear explosion, visible as a nova. This process does not destroy the white dwarf, allowing for the possibility of recurrent novae.
