The absolute magnitude of a star is defined to be the apparent magnitude that the star would have if it were at a standard distance of _____ parsec(s).

What is the likely final fate of a star whose mass is 25 solar masses after it has finished its nuclear burning phases?

Extremely high mass (20-30 solar masses) stars have large cores. When they die they will most likely end up as a
