Is a pulsar a white dwarf?
A pulsar is a type of neutron star, a collapsed core of an extremely massive star that exploded in a supernova. Whereas white dwarfs have incredibly high densities by earthly standards, neutron stars are even denser, cramming roughly 1.3 solar masses into a city-sized sphere.
How hot is a pulsar?
A Pulsar is nothing more than a neutron star which points towards Earth [See related question] A newly formed neutron star would have a temperature of 1011 - 1012 Kelvin, but after a year, it will cool down to 106 (a million) Kelvin, due to the large number of neutrinos it emits.
How do stars more massive than four solar masses evolve into neutron stars?
I've seen that figure of 4 times the Sun's mass, but the usual number given is at least 8 times the Sun's mass. Anyway here's the answer: The general idea is that, depending on how much mass is left once the star runs out of fuel, it may become a white dwarf, a neutron star, or a black hole. A star like the Sun goes through a "red giant" star stage then becomes white dwarf star. Stars that are much more massive than the Sun go through a "supergiant" stage. They finally run out of fuel. The core of the star is now mainly iron. If, after running out of fuel, the amount of mass left in the core is more than a certain limit - the Chandrasekhar limit, currently believed to be about 1.39 times the mass of the Sun - the core's "electron degeneracy" pressure is not enough to resist the gravitational force on the core. In this case, the core of the star collapses into a neutron star or black hole and causes a supernova explosion.
Is the troposphere denser in winter than summer?
Yes. Cold air is denser than warm air and thus the troposphere is denser in the winter than in the summer.
Why are neutron stars so dense?
The black hole is infinitely more dense than a neutron star. The neutron star is something like the mass of upto 2.3 suns compressed into a ball a dozen or so kilometers in diameter. That makes the neutron star about as dense as the nucleus of an atom. Really dense stuff. Like a couple of million pounds per cubic inch, maybe. The density of the neutron star varies from "less" near the surface to many times "more" near the center. But the black hole has infinite density. That makes it infinitely more dense than a neutron star. A teaspoon of neuton star has more mass than the entire human population
Is a red giant star denser than a neutron star?
A neutron star is the densest object known to us. (Apart from a black hole). See related question.
Which is denser a dwarf star or a giant star?
A dwarf star is denser than a giant star. Dwarf stars have a higher density due to their smaller size and higher mass compared to giant stars. Giant stars have larger volumes and lower densities as they have expanded and become less dense towards the end of their life cycle.
Is a Red Giant star larger than a neutron star?
Yes, a Red Giant star is typically much larger than a neutron star. Red Giants are evolved massive stars that have expanded and cooled, while neutron stars are extremely dense remnants of supernova explosions that are only about 10-20 kilometers in diameter.
Why do you think some smaller planet are heavier than the bigger ones?
They are much denser. it's the same with stars and neutron stars. Neutron stars are many times smaller than the original star but much heavier because they are so denser
Is the density of a neutron star about the same density as a white dwarf?
No, the density of a neutron star is much higher than that of a white dwarf. Neutron stars are composed mostly of densely packed neutrons, while white dwarfs are made of electron-degenerate matter. Neutron stars are some of the densest objects in the universe.
Is a neutron star bigger than a planet?
Yes, a neutron star is much more massive and denser than a planet. Neutron stars are formed from the remnants of massive stars and are typically only a few kilometers in diameter, while planets can be thousands of kilometers in size.
Which star is larger neutron star or subgiant star?
A subgiant star is larger than a neutron star. Neutron stars are incredibly dense and compact remnants of massive stars, while subgiant stars are in a transitional phase between main sequence and red giant stages, typically larger and more diffuse than neutron stars.
What object is even denser than a neutron star?
Nothing known is denser than the densest of neutron stars except a gravitational singularity (Black hole). The upper limit of the inward pressure a neutron star can handle before further implosion is dictated by neutron degeneracy pressure. However, theoretically (Not yet observed but probably out there) the next step would be a quark star, that is, a star that is held from implosion by quark degeneracy pressure. Then the next stage would be a black hole. Technically there is yet another stage in between a qaurk star and a singularity called preon degeneracy prssure but the preon models are too flawed to even consider.
What 2 things can happen to a star after a supernova?
It can either become a neutron star or a black hole. If the star is between 8 and 15 solar masses, it will become an incredibly dense neutron star. If it is more than 15 solar masses, it will collapse and become an even denser black hole.
Is a nebula larger than a neutron star?
Yes, a nebula is far larger than a neutron star. A neutron star is a few miles across. A nebula is light years across.
Can a planet be denser than its star?
Yes, the Earth is much denser than our sun.
Can a neutron star become a nebula?
No, a neutron star can't become a nebula. A neutron star is not made of atomic matter, has less mass than a nebula, and has no mechanism by which to expand.
