Composition -modes and -modes of neutron stars with gravitationally coupled dark matter: degeneracy with the symmetry energy
Probit J Kalita, Bharat Kumar, H C Das
Composition gravity () modes have been proposed as a probe of dark matter in neutron stars, on the basis of one-fluid models in which the dark matter is in chemical equilibrium…
Quarkyonic matter suppresses neutron-star modes and reverses their mass trend
Probit J Kalita, Bharat Kumar
Gravity (g) modes are the only neutron-star oscillations that report on the composition of dense matter rather than on its stiffness, and work on hybrid stars has established that…
Trace anomaly and interior curvature of neutron stars in energy-momentum squared gravity
Ratikanta Swain, Sayantan Ghosh, Bharat Kumar
In energy-momentum squared gravity (EMSG), the spacetime inside a neutron star is sourced by effective thermodynamic variables that need not coincide with the physical fluid pressu…
Observable Signatures of a Quarkyonic Phase in Neutron Stars
Probit J Kalita, Tuhin Malik, Tianqi Zhao +2
Quarkyonic matter in \(β\)-equilibrium is a potential description of cold dense matter in neutron stars (NSs), that introduces non-interacting quarks alongside nucleons and leptons…
Spacetime Curvature as a Probe of Exotic Core Phases in Neutron Stars within Modified Gravity
Sayantan Ghosh, Bharat Kumar, Subhash Mahapatra
In this study, we investigate the effect of Energy-Momentum Squared Gravity (EMSG) on the curvature of neutron stars (NSs) by using three relativistic mean-field (RMF) equations of…
