Dark Matter in Compact Stars

Studying how fermionic and bosonic dark matter modifies the structure, stability, and observable properties of neutron stars using a relativistic two-fluid framework. Constraints from NICER, GW170817, and PSR J0952-0607.

Neutron Star Cooling

Modelling thermal evolution of neutron stars including superfluidity, pairing gaps, and direct URCA processes. Constraining gap parameters using observed surface temperature data and mass distributions.

Thermal Evolution Superfluidity Pairing Gaps URCA Process

Gravitational Waves & Oscillations

Computing inspiral waveforms, f-mode and r-mode oscillation frequencies, and tidal Love numbers for dark matter admixed neutron stars. Connecting to multi-messenger observations from LIGO–Virgo–KAGRA.
