Question

identify the properties by whether they are characteristic of novae, supernovae, or both. novae both supernovae answer bank involve a temporary increase in brightness progenitor can be a white dwarf can result in an explosion that blows off most of the mass of the progenitor can happen repeatedly from the same star

Explanation:

Novae are characterized by a temporary increase in brightness and can happen repeatedly from the same star. Both novae and supernovae can have a white - dwarf as a progenitor. Supernovae result in an explosion that blows off most of the mass of the progenitor.

Answer:

Novae: involve a temporary increase in brightness, can happen repeatedly from the same star
Both: progenitor can be a white dwarf
Supernovae: can result in an explosion that blows off most of the mass of the progenitor
