When a medium-size star runs out of fuel (hydrogen to fuse into helium), it will collapse on itself. It has a large enough mass that it can push past the resistance from electron degeneracy pressure. When it collapses more, it will get stopped by neutron degeneracy pressure. It will settle at a star that is about 20 kilometers in diameter. The star fuses protons with electrons, and these form neutrons to make a kind of "neutron soup".
All young neutron stars in reality are "pulsars". However, for a neutron star to be termed a pulsar, it's magnetic axis has to point towards Earth. (So we can see the pulse, even though all young neutron stars have a pulse, they cannot be observed from Earth.)
"explode as supernovae". These are called Type II supernovae and sometimes a neutron star is formed, not a black hole.
The three corpses of stars are white dwarfs, neutron stars, and black holes. White dwarfs are remnants of low to medium-mass stars that have shed their outer layers, leaving behind a hot core. Neutron stars form from the collapse of massive stars in supernova explosions and are incredibly dense, composed mostly of neutrons. Black holes result from the gravitational collapse of very massive stars, creating regions in space with gravity so strong that not even light can escape.
The name "neutron star" some from the fact that the neutron star is mainly composed of neutrons. The gravitational pull of a neutron star is so strong that most matter are crushed into neutrons.
Neutron degeneracy pressure, in which the neutrons themselves prevents further collapse.
Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.
Stars that are too massive to form neutron stars can undergo a supernova explosion and collapse into a black hole. This process occurs when the core of the star collapses under its own gravity, creating a region with infinite density and strong gravitational pull from which not even light can escape.
Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.
Yes, both black holes and neutron stars are remnants of the death of massive stars. Neutron stars form when the core of a massive star collapses but does not produce a black hole. Black holes are formed when the core of a massive star collapses beyond the neutron star stage.
Mostly in galaxies, where they can form Super Massive Black Holes.
No, black holes cannot turn into neutron stars. Neutron stars form from the remnants of supernova explosions of massive stars, while black holes are formed from the gravitational collapse of massive stars. Once a black hole is formed, it will remain a black hole and will not transform into a neutron star.
Stars that become white dwarfs die but become black holes . Neutron stars are born from a Super Nova that stored its energy and became a neutron star.
First [may be partial] is: A Cephid Variable Star. Quasars and other Gamma Ray sources [colliding Neutron Stars, and 'coalescing' Pairs of Black Holes for example] are also closely related.
No, not all neutron stars are pulsars. Pulsars are neutron stars that emit beams of radiation that are detectable from Earth as rapid pulses of light. While many neutron stars are pulsars, not all neutron stars exhibit this pulsing behavior.
A pulsar
No, not all neutron stars are pulsars. Pulsars are a type of neutron star that emits beams of radiation, which can be detected as pulses of light. Some neutron stars do not emit these beams and are not classified as pulsars.
Neutron stars are incredibly dense remnants of massive stars that have undergone supernova explosions. They primarily create strong gravitational and magnetic fields, which can lead to the emission of intense radiation, particularly in the form of X-rays and gamma rays. Additionally, neutron stars are considered potential sources of gravitational waves, especially when they merge with other neutron stars or black holes. Their exotic conditions also provide insights into fundamental physics, including the behavior of matter at extreme densities.
