Answer to Question 1

No, ours is a single star, with no close companion to supply fresh hydrogen via mass transfer onto the surface of our collapsed white dwarf Sun billions of years from now.

Answer to Question 2

When a white dwarf pulls mass off its companion in a mass-transfer binary. When this hydrogen shell reaches 10 million K, sudden proton-proton fusion generates the bright flash and rapidly expanding envelope we observe from Earth.
