Web19 okt. 2024 · Neutron stars are made when living stars with masses above roughly 8 solar masses die. This process is a very violent explosion called a supernova, which is triggered when nuclear fusion in the core comes to a halt. There can be nothing to balance the inwards gravity if the outwards pressure from fusion is ended. WebAs the gas is pulled from the normal star down to the surface of the neutron star, the gravitational energy of the neutron star heats the gas to millions of degrees. The hot gas gives off X-rays that mark for us the location of the otherwise invisible neutron star. WebA neutron star does not generate any light or heat of its own after its formation. Over millions of years its latent heat will gradually cool from an intial 600,000 degrees Kelvin (1 million degrees Fahrenheit), eventually ending its life as the cold, dead remnant of a once-glorious star.
