Influence of dark matter on hybrid and twin stars
H. C. Das
We investigate the impact of dark matter (DM) on hybrid and twin stars within a two-fluid framework, where DM and normal matter interact only through gravity. A self-interacting fe…
Cooling of dark neutron stars
B. X. Zhou, H. C. Das, J. B. Wei +3
We study the cooling of isolated dark-matter-admixed neutron stars, employing a realistic nuclear equation of state and realistic nuclear pairing gaps, together with fermionic dark…
Effects of asymmetric dark matter on a magnetized neutron star: A two-fluid approach
Pinku Routaray, Vishal Parmar, H. C. Das +3
We study the interaction between dark matter (DM) and highly magnetized neutron stars (NSs), focusing on how DM particle mass, mass fraction, and magnetic field (MF) strength affec…
Neutron Decay Anomaly and Its Effects on Neutron Star Properties
H. C. Das, G. F. Burgio
We investigate the effects of dark matter (DM) on neutron star (NS) properties using the neutron decay anomaly model within the relativistic mean-field (RMF) framework. Three nucle…
Critical States of Fermions with Flux Disorder
Hiranmay Das, Naba P. Nayak, Soumya Bera +1
Motivated by many contemporary problems in condensed matter physics where matter particles experience random gauge fields, we investigate the physics of fermions on a square lattic…
Astrophysical constraints on neutron star -modes with a nonparametric equation of state representation
Sailesh Ranjan Mohanty, Utkarsh Mali, H. C. Das +2
We constrain the fundamental-mode (-mode) oscillation frequencies of nonrotating neutron stars using a phenomenological Gaussian process model for the unknown dense-matter equat…
