Compact Stars as Dark Matter Probes

TL;DR

This paper explores how compact stars like white dwarfs and neutron stars can serve as sensitive probes for dark matter, providing constraints on dark matter density and particle properties through their accretion effects.

Contribution

It demonstrates that compact stars can be used to constrain dark matter parameters in regions of the parameter space where their accretion effects are significant.

Findings

Compact stars are sensitive to dark matter accretion in large parameter regions.

Constraints on dark matter density can be derived from observations of compact stars.

Physical properties of dark matter particles can be inferred from their effects on compact stars.

Abstract

We discuss the consequences of the accretion of dark matter (DM) particles on compact stars such as white dwarfs and neutron stars. We show that in large regions of the DM parameter space, these objects are sensitive probes of the presence of DM and can be used to set constraints both on the DM density and on the physical properties of DM particles.
