Evolution and mergers of eccentric white dwarf binaries encountering intermediate-mass black holes
Adarsh Pandey, Aryabrat Mahapatra, Tapobrata Sarkar
We study how a close passage past an intermediate-mass black hole (IMBH) changes the evolution of an eccentric white dwarf (WD) binary that has nominal Roche lobe overflow at inter…
Relativistic Tidal Disruption in Black Hole and Wormhole Backgrounds
Pritam Banerjee, Kowsona Chakraborty, Niles Mondal +1
Black holes (BHs) and wormholes (WHs) are characterized by distinct spacetime geometries, whose differences become pronounced close to the central objects. A useful way to probe su…
Tidal encounters of close white dwarf binaries with spinning black holes
Aryabrat Mahapatra, Adarsh Pandey, Pritam Banerjee +1
When a stellar binary encounters a spinning black hole, interesting phenomena might result due to the mutual interaction between the binary spin, orbital angular momentum and the b…
Tidal disruptions of close white dwarf binaries by intermediate mass black holes
Aryabrat Mahapatra, Adarsh Pandey, Pritam Banerjee +1
We perform a suite of numerical simulations of tidal disruption events, using smoothed particle hydrodynamics, for a close binary system consisting of two low-mass white dwarfs, an…
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…
Geometric Critical Exponents in Classical and Quantum Phase Transitions
Prashant Kumar, Tapobrata Sarkar
We define geometric critical exponents for systems that undergo continuous second order classical and quantum phase transitions. These relate scalar quantities on the information t…
