What result might you expect in a binary system containing a white dwarf with a mass considerably below 1.4 M?

Question

Quizplus · Accepted Answer

A white dwarf with a mass below 1.4 M is not massive enough to undergo a Type Ia supernova, which requires the white dwarf to reach the Chandrasekhar limit. However, if the white dwarf is in a binary system and accretes matter from its companion star, it can reach a temperature and density high enough to trigger a runaway fusion reaction and result in a nova.
