Pulsar kicks are produced when a type Ia supernova occurs with a neutron star core remnant. The neutron star is then given a kick, a back-reaction of the supernova explosion. There are three main types of mechanisms which can produce this kick: a hydrodynamical mechanism, a magnetic-neutrino driven mechanism, and an electromagnetic mechanism. Based on ...

Type Ia supernovae are thought to be the result of a thermonuclear explosion in a white dwarf that is approaching the Chandrasekhar mass limit. The properties of the supernova explosion, including its energy, depends significantly on the way in which the thermonuclear runaway begins.
