Effects of Dark Matter on $f$-mode oscillations of Neutron Stars

Understand

The effect of dark matter (DM) on $f$-mode oscillations in DM admixed neutron stars (NSs) is investigated in a comprehensive analysis with particular attention to the role of the nuclear equation of state.

• Hadronic matter is modeled by the relativistic mean field model and the DM model is based on the neutron decay anomaly.
• The non-radial $f$-mode oscillations for such DM admixed NS are studied in a full general relativistic framework.
• We investigate the impact of DM, DM self-interaction, and DM fraction on the $f$-mode characteristics.
