During most of its lifetime, a star maintains an equilibrium size inwhich the inward force of gravity on each atom is balanced by anoutward pressure force due to the heat of the nuclear reactions inthe core. But after all the hydrogen "fuel" is consumed by nuclearfusion, the pressure force drops and the star undergoes agravitational collapse until it becomes a neutron star. In a neutronstar, the electrons and protons of the atoms are squeezed togetherby gravity until they fuse into neutrons. Neutron stars spin veryrapidly and emit intense pulses of radio and light waves, one pulseper rotation. These "pulsing stars" were discovered in the 1960s andare called pulsars.Part AA star with the mass (M = 2.0 × 10³0 kg) and size (R = 3.5 × 108 m) of our sun rotates once every 33.0 days.
