Neutron star oscillations from starquakes | |||||

Abstract |
Glitches - sudden increases in spin rate - are observed in many pulsars. One mechanism that has been proposed to account for these glitches is the starquake model, in which they are triggered by a sudden loss of strain from the solid crust of the star. Starquakes can be expected to excite oscillation modes of the neutron star, which means that they are of interest as a source of gravitational waves. We describe a model that we are developing to calculate changes in the strain distribution of the star during a starquake, in order to work out how it oscillates after the glitch. |
