Gravitational wave echoes as probes of the maximum mass of strange stars in quadratic curvature-matter coupled gravity

Debadri Bhattacharjee, Pradip Kumar Chattopadhyay, Kazuharu Bamba

Gravitational wave astronomy provides an exemplary avenue to study exotic compact stars with utmost precision. Recent analyses of GW170817 have reported possible post-merger gravit…

Influence of chemical potential to explain the maximum mass and tidal love number of strange stars

Debadri Bhattacharjee, Pradip Kumar Chattopadhyay

We investigate the influence of medium effects on strange quark matter and their consequences for the structural properties of compact stars. In this study, the bag constant, in th…

Maximum mass limit of strange stars in quadratic curvature-matter coupled gravity

Debadri Bhattacharjee, Pradip Kumar Chattopadhyay, Kazuharu Bamba

We explore the maximum mass limit of strange stars in quadratic curvature gravity with the non-minimal matter coupling. The characteristic parameters of the quadratic curvature cou…

Hybrid compact stars with finite strange quark mass and dark energy: implications for astrophysical observations

Rohit Roy, Koushik Ballav Goswami, Debadri Bhattacharjee +1

In this work, a detailed investigation of compact stars composed of deconfined quark matter with finite strange quark mass () admixed with dark energy is presented. The…

Thermodynamic invariance of the energy-momentum tensor under matter-Lagrangian choices and its astrophysical implications in gravity

Debadri Bhattacharjee, Pradip Kumar Chattopadhyay

The correct choice for the matter Lagrangian in the framework of theory of gravity, has been a fundamental yet often overlooked ambiguity. It has been…
