Black hole

Vedclass · Answer

(B) According to stellar evolution theory,stars with an initial mass significantly greater than the mass of the Sun $(M)$ undergo a supernova explosion at the end of their life cycle.After the red giant phase,if the remaining core mass is sufficiently large (typically greater than $3\, M$),the gravitational collapse continues until it forms a black hole.Therefore,for a star with an original mass greater than $5\, M$,the final remnant is a black hole.

When the original mass of a star is greater than $5\, M$ ($M =$ mass of the sun),the death of this star will give rise to:
