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…
Exploring Radial Oscillations in Slow Stable and Hybrid Neutron Stars
Sayantan Ghosh, Sailesh Ranjan Mohanty, Tianqi Zhao +1
In the era of gravitational wave astronomy, radial oscillations hold significant potential for not only uncovering the microphysics behind the internal structure but also investiga…
Probing the impact of Delta-Baryons on Nuclear Matter and Non-Radial Oscillations in Neutron Stars
Probit Jyoti Kalita, Pinku Routaray, Sayantan Ghosh +2
The presence of heavy baryons, such as -baryons and hyperons can significantly impact various properties of Neutron Stars (NSs), like oscillation frequencies, dimensionless tida…
Exploring the Macroscopic Properties and Nonradial Oscillations of Proto-Neutron Stars: Effects of Temperature, Entropy, and Lepton Fraction
Sayantan Ghosh, Shahebaj Shaikh, Probit J Kalita +3
Neutron stars (NSs) have traditionally been viewed as cold, zero-temperature entities. However, recent progress in computational methods and theoretical modelling has opened up the…
The Impact of Anisotropy on Neutron Star Properties: Insights from I-f-C Universal Relations
Sailesh Ranjan Mohanty, Sayantan Ghosh, Pinku Routaray +2
This study presents a universal relation for anisotropic neutron stars, called the relation, which accounts for the local anisotropic pressure using the Quasi-Local (QL) Mo…
Investigating Dark Matter-Admixed Neutron Stars with NITR Equation of State in Light of PSR J0952-0607
Pinku Routaray, Sailesh Ranjan Mohanty, H. C. Das +4
The fastest and heaviest pulsar, PSR J0952-0607, with a mass of , has recently been discovered in the disk of the Milky Way Galaxy. In response to this dis…
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…
Radial oscillations in neutron stars from unified hadronic and quarkyonic equation of states
Souhardya Sen, Shubham Kumar, Athul Kunjipurayi +3
We study radial oscillations in non-rotating neutron stars by considering the unified equation of states (EoSs), which support the 2 M star criterion. We solve the Sturm-Li…
