No pretty sure its a black dwarf. Thats when it loses its light completely.

Isn't a supernova caused by the the star collapsing and then exploding, rather than by the star expanding?

Nothing light completly unless its a black hole. Quite a difference between a black hole and a black dwarf!!

I thought a supernova is caused because there is less and less fusion happening so radiation pressure is able to expand and cause the star to explode. As for the white dwarf/black dwarf, the black dwarf is the final stage it comes after the white dwarf and occurs when the "light completely fades" which is what it says in the CGP books :) but great quiz
