abstract

We consider the effect of density dependent dark matter on the neutron star mass, radius, and tidal deformability. Nuclear matter (normal matter) as well as the fermionic dark matter sector is considered in a mean field model. We adopt the two fluid formalism to investigate the effect of dark matter on the neutron star properties. In the two fluid picture, there is no direct interaction between the dark matter and the nuclear matter. Rather these two sectors interact only through gravitational interaction. The nuclear matter sector is described by the $\sigma-\omega-\rho$ meson interaction in the "FSU2R" parameterization. In the dark matter sector, we use the Bayesian parameter optimization technique to fix the unknown parameters in the dark matter equation of state. In the two fluid picture, we solve the coupled Tolman-Oppenheimer-Volkoff (TOV) equations to obtain the mass and radius of dark matter admixed neutron stars (DANSs). We also estimate the effect of the density dependent dark matter sector on the tidal deformability of dark matter admixed neutron stars (DANSs).

  1. Rotating Fermion-Boson Stars in $R$-squared Gravity

    gr-qc 2026-07 conditional novelty 6.0 of 10

    R-squared gravity enlarges the equilibrium domain of rotating fermion-boson stars and raises static and Keplerian maximum masses relative to GR while remaining compatible with current compact-object constraints.

  2. Effects of dark matter and magnetic field on neutron star properties in relativistic mean-field theory: A single-fluid approach

    astro-ph.HE 2026-07 conditional novelty 4.0 of 10

    Fermionic dark matter and strong central magnetic fields both reduce neutron-star maximum mass and radius and lower tidal deformability in single-fluid RMF models, remaining compatible with GW/NICER constraints over t...

  3. Effect of Dark matter and $\sigma$-cut potential on radial and non-radial oscillation modes in neutron stars

    astro-ph.HE 2025-07 conditional novelty 4.0 of 10

    Dark matter-admixed neutron stars oscillate at higher f- and p1-mode frequencies than ordinary or σ-cut models, while quasi-universal oscillation relations still hold.
