A Potential Black Hole Mimicker From Non-Minimal Coupling
Debanjan Debnath, Rikpratik Sengupta, Kaushik Bhattacharya
We present a class of horizonless, regular ultra-compact objects arising in a theory of gravity which allows curvature-fluid coupling. The non-minimal interaction between fluid var…
Junction Conditions and Gravitational Collapse in Scalar-Tensor-Vector Gravity
Debanjan Debnath, Anant Badal, Kaushik Bhattacharya
We formulate the junction conditions for Scalar-Tensor-Vector Gravity (STVG/MOG), proposed by J.~W.~Moffat. Using these conditions, the theory of gravitational collapse is construc…
Spherically Symmetric, Static Solutions in Presence of Matter-Curvature Coupling
Debanjan Debnath, Kaushik Bhattacharya
In this work we have proposed some spherically symmetric, static spacetimes in a theory of gravity which permits non-minimal coupling (NMC) between curvature of spacetime and fluid…
End equilibrium state of a spherical gravitational collapse in the presence of matter and scalar field
Debanjan Debnath, Dipanjan Dey, Kaushik Bhattacharya
We explore the possibilities of modeling a spherically symmetric static spacetime that can emerge as the end state of gravitational collapse, by considering it to be seeded by a co…
