Massive Perturbers and Transient Pickup Discs in Disc-Crossing Encounters in OJ 287-like Supermassive Black Hole Binaries

Debojyoti Garain, Jonathan Zrake, Zoltan Haiman

We study the hydrodynamical response of a massive black hole accretion disc punctured by a lower mass black hole on an inclined, eccentric orbit, as motivated by the quasi-periodic…

Partial tidal disruption of White Dwarfs in off-equatorial orbits around Kerr black holes

Aryabrat Mahapatra, Adarsh Pandey, Debojyoti Garain +1

We present the results of a suite of numerical simulations using smoothed particle hydrodynamics to study partial tidal disruption events (TDEs) of white dwarfs (WDs) in off-equato…

Partial tidal disruptions of spinning eccentric white dwarfs by spinning intermediate mass black holes

Debojyoti Garain, Tapobrata Sarkar

Intermediate-mass black holes (IMBHs, ) are often dubbed as the missing link between stellar mass () and super-massive ($\gtrsim 10…

Fallback rates in partial tidal disruptions of white dwarfs by intermediate mass black holes

Debojyoti Garain, Tapobrata Sarkar

Fallback rate of debris after a partial tidal disruption event of a star with an intermediate mass black hole (IMBH) might provide important signatures of such black holes, compare…

Tidal disruption of white dwarfs in a modified gravity theory with SPH

Debojyoti Garain, Pritam Banerjee, Shaswata Chowdhury +1

Low energy imprints of modifications to general relativity are often found in pressure balance equations inside stars. These modifications are then amenable to tests via astrophysi…

Deviation in stellar trajectory induced by asymmetry in partial tidal disruption

Pritam Banerjee, Debojyoti Garain, Shaswata Chowdhury +3

We study partial tidal disruption and present a quantitative analysis of the orbital dynamics of the remnant self-bound core. We perform smoothed particle hydrodynamical simulation…

Stable Hydrogen burning limits in rapidly rotating very low mass objects

Shaswata Chowdhury, Pritam Banerjee, Debojyoti Garain +1

We present novel effects of uniform rapid stellar rotation on the minimum mass of stable hydrogen burning in very low mass stars, using an analytic model, and relaxing the assumpti…

A stellar constraint on Eddington-inspired Born-Infeld gravity from cataclysmic variable binaries

Pritam Banerjee, Debojyoti Garain, Suvankar Paul +2

Eddington-inspired Born-Infeld gravity is an important modification of Einstein's general relativity, which can give rise to non-singular cosmologies at the classical level, and av…

Constraining modified gravity from tidal phenomena in binary stars

Pritam Banerjee, Debojyoti Garain, Suvankar Paul +2

In beyond-Horndeski theories of gravity, the Vainshtein screening mechanism might only be partially effective inside stellar objects. This results in a modification of the pressure…
