MHD simulations of resistive viscous accretion disk around millisecond pulsar
M. Čemeljić, V. Parthasarathy, W. Kluźniak
We perform MHD simulations of a thin resistive and viscous accretion disk around a neutron star with the surface dipolar magnetic field of 10 Gauss. The system evolution is fol…
MHD simulations of oscillating cusp-filling tori around neutron stars -- missing upper kHz QPO
Varadarajan Parthasarathy, Wlodek Kluzniak, Miljenko Cemeljic
We performed axisymmetric, grid-based, ideal magnetohydrodynamic (MHD) simulations of oscillating cusp-filling tori orbiting a non-rotating neutron star. A pseudo-Newtonian potenti…
Three-dimensional, global, radiative GRMHD simulations of a thermally unstable disc
B. Mishra, P. C. Fragile, L. C. Johnson +1
We present results of a set of three-dimensional, general relativistic radiation magnetohydrodynamics simulations of thin accretion discs around a non-rotating black hole to test t…
Quasi-periodic oscillations of perturbed tori
Varadarajan Parthasarathy, Antonios Manousakis, Wlodek Kluzniak
We performed axisymmetric hydrodynamical simulations of oscillating tori orbiting a non-rotating black hole. The tori in equilibrium were constructed with a constant distribution o…
Oscillations of radiation pressure supported tori near black holes
Grzegorz P. Mazur, Olindo Zanotti, Aleksander Sądowski +2
We study the dynamics of radiation pressure supported tori around Schwarzschild black holes, focusing on their oscillatory response to an external perturbation. Using KORAL, a gene…
