Then I add more hydrogen to make it collapse into a neutron. Pulsars are detected by their rapidly repeating radio signals beamed at Earth from those charged particles trapped in the magnetic field. I am adding hydrogen to earth until it has enough mass to start nuclear fusion and become a star. This type of neutron star is called a pulsar. Charged particles can get caught up in the magnetic fields andД«eam away radiation like a lighthouse lamp. If the magnetic poles are not lined up with the star's rotation axis then the magnetic field spins around very fast. In the future, if a neutron star is able to get close enough to a black hole before plunging in, it could get ripped to pieces and put on a visible fireworks display that astronomers can watch. Some neutron stars spin very rapidly and have very strong magnetic fields. One spoonful of neutron star material on Earth would weigh as much as all the cars on Earth put together. All that remains is the collapsed core, a Neutron Star or sometimes a Black Hole, if the star was really massive.ДЄ typical neutron star is the size of a small city, only 10 Kilometers in diameter but it may have the mass of as many as three suns. It then bounces off the core and blows apart in a supernova. A typical neutron star has about about 1.4 times our sunвЂ™s mass. TheyвЂ™re among the most bizarre objects in the universe. The surface of the star falls down until it hits the now incredibly dense core. These small, incredibly dense cores of exploded stars are neutron stars. When the core collapses the entire star collapses. When a really massive star runs out of nuclear fuel in its core the core begins to collapse under gravity. Neutron Stars are the end point of a massive star's life. What happens when you make the Sun 13 times more massive, have it spinning at 50 000 km/s, have a 5 000 000 G (500 T) magnetic flux density According to th.
