Long timescale numerical simulations of large, super-critical accretion discs
P. Chris Fragile, Matthew J. Middleton, Deepika A. Bollimpalli +1
In this paper, we report on three of the largest (in terms of simulation domain size) and longest (in terms of duration) 3D general relativistic radiation magnetohydrodynamic simul…
Polarization Signatures of Quasi-Periodic Oscillations in Simulated Tilted, Truncated Disks
P. Chris Fragile, Deepika A. Bollimpalli, Jeremy D. Schnittman +1
We utilize the Monte Carlo radiation transport code, Pandurata, to create images, spectra, polarization maps, and light curves from a set of general relativistic magnetohydrodynami…
Asymmetric Jet launching
Aleksandra Kotek, Miljenko Čemeljić, Włodek Kluźniak +1
In resistive and viscous magnetohydrodynamical (MHD) simulations we obtain axial jets launched from the innermost magnetosphere of a star-disk system. We found that in a part of th…
Radial modes of levitating atmospheres around Eddington-luminosity neutron stars
Deepika Ananda Bollimpalli, Włodek Kluźniak
We consider an optically thin radiation-supported levitating atmosphere suspended well above the stellar surface, as discussed recently in the Schwarzschild metric for a star of lu…
Effect of matter geometry on low angular momentum black hole accretion in the Kerr metric
Pratik Tarafdar, Deepika B. Ananda, Sankhashubhra Nag +1
This work illustrates how the formation of energy-preserving shocks for polytropic accretion and temperature-preserving shocks for isothermal accretion are influenced by various ge…
Perturbation of mass accretion rate, associated acoustic geometry and stability analysis
Deepika A Bollimpalli, Sourav Bhattacharya, Tapas K Das
We investigate the stability of stationary integral solutions of an ideal irrotational fluid in a general static and spherically symmetric background, by studying the profile of th…
