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…
Universal Relations and Correlation Analysis of Proto-Neutron Star Properties in Energy-Momentum Squared Gravity
Sayantan Ghosh
Proto-neutron stars (PNSs) are the hot, lepton-rich remnants of the core collapse supernovae, which go through a cooling phase and become cold, stable Neutron stars (NSs). Since PN…
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…
Unstable Anisotropic Neutron Stars: Probing the Limits of Gravitational Collapse
S. R. Mohanty, Sayantan Ghosh, Bharat Kumar
Neutron stars (NSs) are incredibly versatile for studying various important aspects of high-energy and compact-object physics. These celestial objects contain extreme matter at inc…
