CPT Student Seminar: Very preliminary results on DM capture in WDs

Presented by Maura Ramirez-Quezada, IPPP, Durham University
11 November 2019 17:00 in Zoom

Compact stellar objects such as white dwarfs (WDs) have been proposed as potential probes to set constraints on dark matter (DM) particles. When DM scatters off nuclei, kinetic energy is transferred to the star that can give rise to an observational signal. Previous works did not consider relativistic effects on the calculation of the DM capture rate in WDs. However, since WDs are very dense objects, these effects can lead to sizeable corrections to the DM scattering cross-section. We present preliminary results of such computation and also study the impact of the inner structure and finite temperature of these stars on the DM capture rate.
