asap format a paragraph that answers these questions. remember no one word answers. how does the post-main-sequence evolution of a low-mass star differ from that of a high-mass star? what stellar remnants are associated with each?

Red giant white dwarf ⟶ black dwarf  

Red giant   supernova ⟶ neutron star

Red giant supernova ⟶ black hole

Explanation:

Low-mass Stars

As the core of a red giant collapses collapses, the outer layers are expelled to form a planetary nebula, while the core becomes a white dwarf.

The white dwarf cools to form a black dwarf.

High-mass stars

As high-mass stars collapse, their core temperatures increase as carbon fuses to form heavier elements, ending with the most stable one, iron.

Gravitational collapse crushes the iron atoms together. Nuclear repulsions overcome the force of gravity and the star erupts in a massive supernova explosion.

If the star has 8 to 20 solar masses, the remnant will collapse of its own gravity and become a neutron star.

If the star has more than 20 solar masses, the force of gravity is so great that the remnant collapses to a black hole.
