A star that cannot undergo further fusion after it has exhausted its nuclear fuel is a white dwarf. Once a star like our Sun has burned through its hydrogen and helium, it sheds its outer layers, leaving behind a hot core that cools over time. This remnant is no longer capable of nuclear fusion and will gradually fade away as it radiates its remaining heat into space. Eventually, it will become a cold, dark object known as a black dwarf, although the universe is not old enough for any black dwarfs to exist yet.
No. That is when stars run out of hydrogen. They then have helium for fuel.
Yes, all stars run on a limited suppliy of fuel - mainly hydrogen. Some stars burn it very quickly but reach high temperatures, while other lower mass stars burn their fuel more slowly, lasting for longer, but burn at cooler temperatures.
Red giant.
When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
A neutron star is already the remains of a massive star that has run out of fuel.
No. That is when stars run out of hydrogen. They then have helium for fuel.
Yes. A white dwarf is a compact star, the remnant of a star that has run our of fuel.
They will all eventually run out of fuel.
This will happen when the star starts to run out of hydrogen fuel.
Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.
It typically takes around 10 billion years for a star like the sun to consume all its hydrogen fuel and enter a different phase of its life cycle. The exact duration can vary depending on the size and type of the star.

Yes - in the sense that it no longer produces energy. In other words, the star has run out of fuel for nuclear fusion.
