Webexplains pulsars as spinning neutron stars that emit beams of radiation from their magnetic poles. As they spin, they sweep the beams around the sky like lighthouses; if the beams sweep over Earth, astronomers detect pulses. Neutron Star. When a supernova explodes, the core collapses to a very small size. Theory predicts that the collapsing ... WebPulsating stars. An impressive body of evidence indicates that stellar pulsations can account for the variability of Cepheids, long-period variables, semiregular variables, Beta …
