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?
white drawf
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.
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 a white dwarf bigger than a main sequence?
No. A white dwarf is the collapsed remnant of the core of a low to medium mass star. It has a mass comparable to that of a star, but is about the size of a small planet.
What is is a cold dead star called?
white drawf
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.
Is a white dwarf bigger than a main sequence?
No. A white dwarf is the collapsed remnant of the core of a low to medium mass star. It has a mass comparable to that of a star, but is about the size of a small planet.
The color of a star is what?
The color of a star is its . . . color. In other words, a star's color shows us how white-hot it is. Some stars, like our Sun, are colored slightly in the yellow direction of white-hot. Bigger stars are less yellow and more blue - the bigger, the hotter, the bluer shade of white-hot they are. Red giants, white dwarfs and black holes are something related, but different.
