Dark Matter Effects on the Compact Star Properties

Understand

The neutron star properties are generally determined by the equation of state of $\beta$-equilibrated dense matter.

• In this work, we consider the interaction of fermionic dark matter (DM) particles with the nucleons via Higgs exchange and investigate its effect on the neutron star properties with the relativistic mean-field model equation of state coupled with DM.
• We deduce that DM significantly affects the neutron star properties, such as considerably reduce the maximum mass of the star, which depends on the percentage of the DM considered inside the neutron star.
• The tidal Love numbers both for electric and magnetic cases and surficial Love numbers are also studied for DM admixed NS.
