What is the final remnant left behind by a low or intermediate mass star, like the Sun, after the Red Giant phase concludes?

Answer

A white dwarf supported by electron degeneracy pressure

After the outer layers of a Sun-like star are expelled as a planetary nebula, the hot, dense core remains. This remnant, a white dwarf, is prevented from collapsing further by electron degeneracy pressure.
