neutron stars
Leftover materials from a star explosion, specifically a supernova, are called supernova remnants. These remnants consist of gas, dust, and heavier elements that are expelled into space during the explosion. Over time, they can contribute to the formation of new stars and planets as they mix with surrounding interstellar material. Notable examples of supernova remnants include the Crab Nebula and the Cassiopeia A.
The leftover center of an old star can become either a white dwarf, neutron star, or black hole, depending on its original mass. A white dwarf forms from stars like our Sun, where the outer layers are shed, leaving a hot core that gradually cools. Neutron stars arise from more massive stars that undergo supernova explosions, resulting in a dense core primarily composed of neutrons. If the original star is sufficiently massive, it can collapse into a black hole after its supernova phase.
It is an adverb phrase, although in forms such as "The period after a supernova is marked by stellar collapse" it seems to be an adjective phrase.
When a large star collapses in a supernova, it can produce either a neutron star or a black hole, depending on the mass of the original star. A neutron star forms when the core of the star collapses but the outer layers are ejected, while a black hole forms when the core collapses completely.
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.

No. Comets are made from the leftover material when a solar system forms.
A leftover piece of material is commonly referred to as a scrap.
Leftover material can be referred to as scraps, remnants, or remnants.
No, a black hole is not typically a supernova remnant. A black hole is formed when a massive star collapses under its own gravity, creating a region of spacetime from which nothing, not even light, can escape. On the other hand, a supernova remnant is the leftover material from a massive star's explosion in a supernova event.
The material sent into space by a supernova is called supernova ejecta. It includes elements such as hydrogen, helium, carbon, oxygen, and heavier elements created during the supernova explosion.

A material scrap is typically referred to as a waste material, leftover material, or remnant.
