Neutron stars with an agnostic Dark sector: Core and Halo configurations from a two-fluid approach
Asit karan, Asim Kumar Saha, Tuhin Malik +2
The study of dark matter admixed neutron stars has the potential to advance our understanding of dark matter particle candidates. However, the large parameter space of dark matter…

Imprints of Non-Symmetric Dark Matter Halos on Magnetars: A Two-Fluid Perspective
Asit karan, Anil Kumar, Monika Sinha +1
In this study, we investigate the impact of dark matter on the structure and deformation of magnetars. We assume a perturbative approach for the magnetic field deformation and that…

Modification of the universal relation between mass, radius and nonradial -mode oscillation in proto-neutron stars
Deepak Kumar, Asit Karan, Anshuman Verma +2
Neutron stars are usually assumed to be cold; however, in certain dynamical astrophysical scenarios such as newly born neutron stars or binary star mergers, the temperature effects…
