Simply, neutron star is a big nuclear - of 10km radius and solar mass (mass density about 1017- 1018 kg/m3). The material in a white dwarf is supported by electron degeneracy pressure. The physics of degeneracy yields a maximum mass for a non-rotating white dwarf, the Chandrasekhar limit-approximately 1.4 solar masses-beyond which it cannot be supported by electron degeneracy pressure. The density of white dwarf is - 109 kg/m3. So its radius is much bigger 10km, but the mass can be less, as well as bigger of solar mass.

What is is a cold dead star called?
A cold dead star is called a white dwarf. It is formed when a star has exhausted its nuclear fuel and collapsed under gravity, shrinking to a small, dense, and dim object.
What one is bigger a white dwarf or a main sequence star?
Main sequence stars are bigger.
Is the sun larger than a white dwarf?
YES. A typical white dwarf star is only a bit bigger than the Earth.
What is the bigger star?
The bigger star is typically referred to as the one with a higher mass. Size can vary, but mass is a good indicator of a star's overall size and brightness.
Small dense star that remains after a red giant?
"Stellar masses" is not a unit of mass - perhaps you mean "solar masses". Depending on the remaining mass - after the supernova explosion - either a neutron star or a black hole. In the case of four stellar masses, probably a neutron star; it would require a more massive star than that to become a black hole.

Is Pluto a dwafr star?
No, Pluto is a Drawf Planet.
Is a star bigger than a white dwarf?
Yes.
Is it true the store key to Kokomo Toys is located in Grye-Vipersleft goggle?
The key to kokomo toys is made of a burned out drawf star that only Thomas O'Mahony can lift... because he's a drawf.
What one is bigger a white dwarf or a main sequence star?
Main sequence stars are bigger.
Which is bigger a neutron star or a white dwarf?
A white dwarf is much larger than a neutron star.
What size is a white dwarf star?
Generally, they are not much bigger than the Earth.
What is an astronomy white star?
Any star a little bigger than our own Sun (~1 -> 2 times).
Is the sun larger than a white dwarf?
YES. A typical white dwarf star is only a bit bigger than the Earth.
How can a star that has more mass than the sun be smaller than your sun?
The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
Which on is bigger star or planet?
Star
If a star dies what happens?
it depends on the mass. If the star is small and it dies then it will turn into a red giant then a white dwarf. But if the star has enough mass and is bigger than any other star then it will collapse and turn into a black hole.
