Once a medium sized star has consumed all it's fuel it becomes a White Dwarf star (just the extremely dense core of the original star remains composed mainly of carbon). A White Dwarf star will, however, eventually lose it's heat to become a Black Dwarf.
The remains of a star that has no fuel but still glows faintly are called white dwarfs. White dwarfs are very dense, Earth-sized objects that are formed when a low to medium mass star exhausts its nuclear fuel and sheds its outer layers. The residual heat from the white dwarf's formation causes it to glow faintly for billions of years.
A dense core of neutrons that remains after a supernova is known as a neutron star. It forms when the core of a massive star collapses under gravity after exhausting its nuclear fuel, causing the protons and electrons to combine into neutrons. Neutron stars are incredibly dense, with a mass greater than that of the sun compressed into a sphere only about 20 kilometers in diameter. They often exhibit strong magnetic fields and can rotate rapidly, leading to the emission of beams of radiation that may be detected as pulsars.

The remains of a star after a supernova can be classified primarily as either a neutron star or a black hole, depending on the mass of the original star. If the core's mass is below a certain threshold, it may collapse into a neutron star, which is incredibly dense and composed mostly of neutrons. If the core's mass exceeds this limit, it may collapse further into a black hole, where gravity is so strong that not even light can escape. Additionally, the explosion disperses the outer layers of the star into space, creating a supernova remnant.

The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
The small dense remains of a high-mass star are called neutron stars or black holes, depending on the mass of the star. Neutron stars are formed when the core collapses under its own gravity, while black holes are formed when the core collapses into a singularity.

The mass remains the same, the star becomes more and more dense as the volume decreases
The remains of a high mass star could be a neutron star or a black hole, depending on the mass of the original star. Neutron stars are extremely dense and compact objects, while black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape.
The remains of the sun after its nuclear reactions stop is called a white dwarf. It is a dense, Earth-sized remnant made up mostly of carbon and oxygen.
Studying star and star types can be fun, but it can be challenging to remember each type. A Neuron star is a dense, rapidly spinning star.

When a planetary nebula dissipates, what remains is the core of the star that has shed its outer layers. This core, known as a white dwarf, is extremely dense and hot, gradually cooling over billions of years. The planetary nebula itself, which is the glowing gas and dust expelled by the dying star, eventually disperses into space.
