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…
Exploring density dependent B as a suitable parameter in higher dimensional approach with a non-linear equation of state
Koushik Ballav Goswami, Debadri Bhattacharjee, Anirban Saha +1
In this investigation, we present a singularity free interior solution of the Einstein field equation for a class of anisotropic compact objects in dimensions . In accordan…
Maximum mass of singularity-free anisotropic compact stars in Rastall theory of gravity
Sourav Biswas, Debadri Bhattacharjee, Pradip Kumar Chattopadhyay
The current model explores spherically symmetric anisotropic compact stars within the Rastall theory of gravity. By employing the Krori and Barua metric ansatz (K.D. Krori and J. B…
Exploring gravastar-like structures with strongly interacting quark matter shell in the framework of gravity under conformal symmetry
Debadri Bhattacharjee, Pradip Kumar Chattopadhyay
In this work, we investigate gravastar-like structures in static and spherically symmetric space-time within the framework of gravity coupled with conformal symmetry. We hav…
Estimating the mass of the thin shell of gravastars in generalised cylindrically symmetric space-time within the framework of Rastall theory of gravity
Debadri Bhattacharjee, Pradip Kumar Chattopadhyay
This study investigates the gravastars in the framemwork of Rastall theory of gravity in generalised cylindrically symmetric space-time. Following the Mazur-Mottola hypothesis (P.…
Influence of density-dependent bag function on strange stars for non-zero strange quark mass () in gravity consistent with observational validation
Rohit Roy, Debadri Bhattacharjee, Koushik Ballav Goswami +1
In this work, a new class of solution of the Einstein field equation for an isotropic strange star using the modified Mak-Harko type density profile along with the equation of stat…
