What happens when a star 3 times 5 times and 20 times the mass of the sun?

Answer 1

Complete Question here:

For three mass stars (a) a star with a mass three times the mass of the sun, (b) a star with a mass 5 times mass of the sun and (c) a star with a mass 20 times the mass of the sun

--> in each case describe the possible final state of the star after all its fuel is exhausted.

--> comment on the masses, size and density of these states.

--> for each of the end states, briefly describe experimental observations that allow us to find, identify, and verify the existence of object left after star has exhausted its fuel and collapsed to a final state. As an example how do we know that neuron stars exist.

Answer 2

When stars are 3, 5, or 20 times the mass of the sun, they fall into different categories. A 3 solar mass star is likely to become a white dwarf or a neutron star at the end of its lifecycle. A 5 solar mass star is likely to end its life as a supernova, leaving behind either a neutron star or a black hole. A 20 solar mass star is more likely to end its life as a supernova, potentially creating a black hole.
