The Third Law of Black Hole Dynamics in Lovelock Gravity
Jyotirmoy De, Chiranjeeb Singha, Naresh Dadhich
The third law of black hole dynamics states that it is impossible, through any classical perturbation of a stationary configuration, to reduce the surface gravity of a black hole t…
On the stability of the objects of limiting compactness: Black hole and Buchdahl star
Soumya Chakrabarti, Chiranjeeb Singha, Naresh Dadhich
In General Relativity, there exist two objects of limiting compactness, one with a null boundary defining the horizon of a black hole and the other with a timelike boundary definin…
On electrogravity duality and black hole with global monopole
Chiranjeeb Singha, Naresh Dadhich
By resolving the Riemann curvature into electric and magnetic parts, Einstein's equation can accordingly be written in terms of electric (active and passive) and magnetic parts. Th…
Accreting Black Holes radiate classical Vaidya radiation to pave way for Hawking radiation
Naresh Dadhich, Rituparno Goswami
It is well known that locally defined marginally outer trapped surface (MOTS) is null and coincident with the event horizon of an unperturbed static Schwarzschild black hole. This…
