Effects of Time-Dependent Heat Sources On Neutron Star Crust Cooling

Effects of Time-Dependent Heat Sources On Neutron Star Crust Cooling
Research paper
Description: 
Neutron star crust cooling can give insights to the interior composition of the stars. Using dStar and the neutron star cooling simulation code NSCool, a variable mass is accreted onto different neutron star models. Previous accretion simulations have commonly assumed a constant mass accretion over a long epoch; this research investigates the effects of different accreting mass accretion rate distributions and focuses on a periodic Gaussian distribution, with a ner time epoch. The simulations produce plots of mass accretion rate distributions as well as effective temperature and luminosity as viewed by a distant observer over time. The effects on the quiescent cooling curves due to the time-dependent distribution shapes of accreted mass are found to have only short time-scale effects, with differences only noticeable on timescales as on the order of the accretion events.
