Technologies for supporting high-order geodesic mesh frameworks for computational astrophysics and space sciences
V. Florinski, D. S. Balsara, S. Garain +1
Many important problems in astrophysics, space physics, and geophysics involve flows of (possibly ionized) gases in the vicinity of a spherical object, such as a star or planet. Th…
Effects of Magnetic Field Loops on the Dynamics of Advective Accretion Flows and Jets around a Schwarzschild Blackhole
Sudip K. Garain, Dinshaw S Balsara, Sandip K Chakrabarti +1
Magnetic fields advected along with low angular momentum accretion flows predominantly become toroidal due to the strong azimuthal velocity close to a black hole. We study self-con…
Efficient, Divergence-Free, High Order MHD on 3D Spherical Meshes with Optimal Geodesic Meshing
Dinshaw S. Balsara, Vladimir Florinski, Sudip Garain +2
There is a great need in several areas of astrophysics and space-physics to carry out high order of accuracy, divergence-free MHD simulations on spherical meshes. This requires us…
Turbulent dynamo in a weakly ionized medium
Siyao Xu, Sudip K. Garain, Dinshaw S. Balsara +1
The small-scale turbulent dynamo is an important process contributing to the cosmic magnetization. In partially ionized astrophysical plasmas, the dynamo growth of magnetic energy…
General Relativistic Numerical Simulation of sub-Keplerian Transonic Accretion Flows onto Rotating Black Holes: Kerr Spacetime
Jinho Kim, Sudip K. Garain, Sandip K. Chakrabarti +1
We study time evolution of sub-Keplerian transonic accretion flows onto black holes using a general relativistic numerical simulation code. We perform simulations around the black…
Images and Spectra of Time Dependent Two Component Advective Flow in Presence of Outflows
Arka Chatterjee, Sandip K. Chakrabarti, Himadri Ghosh +1
Two Component Advective Flow (TCAF) successfully explains the spectral and tem- poral properties of outbursting or persistent sources. Images of static TCAF with Compton cloud or C…
