A neutron star has slightly more mass than a white dwarf. This results in higher gravitational attraction. As a result, in a white dwarf, the star's mass (roughly the mass of the Sun - may vary in different white dwarves) has a diameter of a few thousand kilometers, and a density of a few tonnes per cubic centimeter. The neutron star, on the other hand, has a diameter of only 20-30 kilometers, and a density of millions of tonnes per cubic centimeter. For comparison, water has a density of 1 gram per cubic centimeter, other substances around us have similar densities; so the density of a white dwarf is millions of times the density of water, while a neutron star has billions of times the density of water.
What else can I help you with?
Does the sun eventually become a neutron star?
No, the sun will not become a neutron star. Neutron stars form from the remnants of massive stars that have undergone a supernova explosion. The sun is not massive enough to undergo this process and will instead evolve into a white dwarf.
Pulsars cannot be spinning white dwarfs because?
because of the great mass of the star, the gravity of it is very high. So after its death, it actually contracts so tightly that even protons and electrons combine to form neutron and thus results to a star called neutron star. If its previous mass is considerably low, then it could have become a white dwarf
What are the differences between a neutron star and a white dwarf?
According to stellar classification [See Link] the proportion of Stars in category O,B those massive enough to be categorised as possible candidates for a black hole, number less than 0.13% while candidates for white dwarfs, category G,K, comprise about 20% of all known stars.{Reinsertion of answerman001 deleted text}This is because white dwarf stars are caused by the sides of a star pulling inward. However, a black hole is caused when a massive star completely collapses inward upon itself, creating a void of sorts, where instead of giving off light and power, it is blank and gives off nothing(black holes do NOT suck as many people believe). As massive stars are less likely to occur than medium and small- sized stars because of the amount of matter needed to make them, therefore we have many more white dwarf stars than we have black holes.I have already answered this question but apperantly someone has deleted it so o.k. it is because most stars are medium sized, extremely condensed, or just plain small, while black holes need stars that are super-sized, or have a few medium stars in close proximaty(is someone could just correct those mistakes i would but i need to watch what i put down ty)More stars have a longer main sequence (low mass stars), which don't swell up to supergiants, they only swell to giants. Low mass stars are more common, and they end up as white dwarfs.
What is the evolutionary end of red giants?
When a red giant runs out of its fuel - helium - it will blow off its outer layers while the inner core collapses to form a white dwarf. The latter will gradually radiate away its energy to become a black dwarf.
How are white dwarfs neutron Stars and black holes alike?
No. White dwarfs, neutron stars, and black holes are three different things. With the exception of some black holes, all are remnants of the cores of dead stars at various degrees of collapse. A white dwarf is the remains of a low to medium mass star consisting of atomic nuclei surrounded by electrons from electron shells that were crushed by gravity. White dwarfs can be up to about two times the mass of the sun and are a few thousand miles across, some about the same size as Earth. A neutron star is a remnant of a massive star that has collapsed even further. In a neutron star the atoms have been crushed so that neutrons are most of what remains. Neutron stars range from 2 to 3 times the mass of the sun and are roughly 12 to 25 miles across. A black hole is the remains of a very massive star that has completely collapsed into, at least theoretically, an infinitely dense point. Around the black hole is an area where gravity is so strong that nothing can escape, not even light. Stellar mas black holes range from 3 to 30 times the mass of the sun. There are also supermassive black holes, which are millions to billions times the mass of the sun. It is not known how supermassive black holes form.
What is the radius of a white dwarf with a mass of 1.5 solar units?
Such a white dwarf could not exist. Above 1.4 solar masses a white dwarf will collapse to form a neutron star.
Does the sun eventually become a neutron star?
No, the sun will not become a neutron star. Neutron stars form from the remnants of massive stars that have undergone a supernova explosion. The sun is not massive enough to undergo this process and will instead evolve into a white dwarf.
What forms when the stars colape?
It depends on the size of the star. You could end up with a White Dwarf, a Neutron Star, or a Black Hole with a White Dwarf coming from the smaller star and and a Black Hole coming from the largest star. Our Sun will leave a White Dwarf when it burns out.
Is it true that when a nova destroys the star and leave behind a white dwarf?
Yes, when a star undergoes a nova, it expels material into space, which can eventually form a white dwarf. A white dwarf is the remnant core of a star that has exhausted its nuclear fuel and collapsed under gravity. Novae are different from supernovae, which are more energetic and can leave behind other remnants like neutron stars or black holes.

What are dead stars called?
Dead stars are commonly referred to by their specific end states depending on their mass. A star that has exhausted its nuclear fuel can become a white dwarf, a neutron star, or a black hole. White dwarfs are the remnants of low to medium-mass stars, while neutron stars and black holes form from the collapse of more massive stars. Each type represents a different phase in the life cycle of a star after it has died.

Will Betelgeuse become a white dwarf?
It's difficult to know exactly what Betelgeuse will become, but it will most likely explode as a supernova. The result will probably be a black hole, but depending on the magnitude of the explosion, it could become a neutron star or pulsar.
How does a white dwarf star or pulsar form?
See related questions.
What is the next stage after The white dwarf stage?
the next stage of a white dwarf is the black dwarf which is form when the degenerate electron slowly cools down by thermal radiation but the time required for a white dwarf to become a black dwarf is bigger than the current age of universe so the evidence of a black dwarf isn't found yet
