Does a star that has no fuel but glows faintly is a black dwarf?
A star that has burned out and no longer has fuel to sustain nuclear fusion in its core is called a white dwarf, not a black dwarf. A white dwarf is the remnant core of a low to medium mass star after its outer layers have been ejected. Over time, a white dwarf will cool down and eventually become a black dwarf, but this process takes billions of years.
How do black holes occur with supernovas?
The usual way a black hole forms is the following. A massive star ends its life in a huge supernova explosion. After that, the star runs out of fuel and collapses, due to its gravity. Actually, any star will collapse, whether it became a supernova or not. A supernova explosion can blow off much of a star's mass into space; in some cases, the star can blow up completely, leaving no remains. In any case, depending on how much mass remains once the star runs out of fuel, what remains will collapse into a white dwarf, a neutron star, possibly a quark star (quark stars are still very hypothetical), or a black hole. The most massive stars become black holes.
What can be either a precursor to a star the remains of a star?
nebula
How does a star turns into a neutron star?
A star 8 time the mass of the Sun turns into a neutron star when it run out of fuel, become a supergiant, and undergo supernova explosion. After the explosion, a core remains. If the core is less than 3 Solar masses, it becomes a neutron star, or else it becomes a black hole.
A star glows because atoms at its center are undergoing nuclear fusion?
Yes, a star glows due to the intense heat and pressure at its core, which causes atoms to undergo nuclear fusion. During this process, hydrogen atoms fuse together to form helium, releasing a tremendous amount of energy in the form of light and heat.
Do star that has no fuel but glows faintly is a black dwarf?
No, it is a red dwarf

When a neutron star runs out of fuel what does it become?
A neutron star is already the remains of a massive star that has run out of fuel.
What is a star called when it glows but has not begun to fuse hydrogen?
Protostar
What remain of a star that has no fuel but glows faintly is a black dwarf?
A black dwarf is a theoretical stellar remnant that is predicted to form when a white dwarf cools down completely. It is essentially a cold, dark, and compact stellar remnant with no nuclear fusion activity. No black dwarfs are currently known to exist in the Universe due to the immense timescales required for white dwarfs to cool down to become black dwarfs.
What happens to a small star when it runs out of fuel?
It loses its outer layers because it has expanded to the point where gravity can no longer hold it together. The inner part of the star becomes a white dwarf, called a white dwarf because it is still glowing with the remaining heat of the dead star. It eventually becomes a black dwarf, where it has radiated all its energy out and no longer glows.
What is the difference in a star than a planet?
a star is way bigger than a planet. you need a telescope to see some of the planets.a star twinkles.a planet glows.
What can be either a precursor to a star or the remains of a star?
A nebula can be a precursor to a star, where gas and dust are slowly collapsing to form a new star. Stellar remnants, like white dwarfs, neutron stars, and black holes, are what remains after a star has gone through its life cycle and exhausted its nuclear fuel.

Is an asteroid considered a shooting star?
No. A shooting star, scientifically called a meteor, is an object from space that is passing through the atmosphere, heating the air until it glows brightly.
