Question

What happens to the lost mass during nuclear reactions in a star's core?

O It is destroyed
O It becomes dark matter
O It is ejected into space
O It is converted to energy

Answer 1

to mass loss, then, stars with starting masses up to at least 8 MSun (and perhaps even more) probably end their lives as white dwarfs. But we know stars can have masses as large as 150 (or more) MSun. They have a different kind of death in store for them. As we will see, these stars die with a bang.
