A New Thermal Source during the Star Quake of Neutron Stars

Based on the hydrostatic equilibrium equation, we obtain two solution for the crust density of neutron star. As the starquake of neutron star induces the crust broken, the density in the crust may transfer from one state to another more stable state. We investigate the electron capture process near the outer crust during the starquake, using a level-to-level transition for calculation of electron capture. We find a new thermal source during the starquake of neutron stars, which may provide a new signal for detecting the activity of neutron stars.
