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…
Investigating quark star properties through baryon number density within the framework of gravity
Sourav Biswas, Debadri Bhattacharjee, Pradip Kumar Chattopadhyay +3
In this paper, we construct a viable strange star model in the framework of the equation of state, , proposed in the MIT bag model, where is termed as t…
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…
