Three Dimensional Simulations of Advective, Sub-Keplerian Accretion Flow onto Non-rotating Black Holes
Sudip K Garain, Jinho Kim
We study the time evolution of sub-Keplerian transonic accretion flow onto a non-rotating black hole using a three-dimensional, inviscid hydrodynamics simulation code. Prior two-di…
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…
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…
General Relativistic Numerical Simulation of sub-Keplerian Transonic Accretion Flows onto Black Holes: Schwarzschild Spacetime
Jinho Kim, Sudip K. Garain, Dinshaw S. Balsara +1
We study time evolution of sub-Keplerian transonic accretion flows onto black holes using a general relativistic numerical simulation code. We perform simulations in Schwarzschild…
On the Linear Stability of Magnetized Jets Without Current Sheets - Relativistic Case
Jinho Kim, Dinshaw S. Balsara, Maxim Lyutikov +1
In our prior papers, we considered the non-relativistic linear stability analysis of magnetized jets that do not have current sheet at the boundary. In this paper, we extend our an…
A High-Order Relativistic Two-Fluid Electrodynamic Scheme with Consistent Reconstruction of Electromagnetic Fields and a Multidimensional Riemann Solver for Electromagnetism
Dinshaw S. Balsara, Takanobu Amano, Sudip Garain +1
In various astrophysics settings it is common to have a two-fluid relativistic plasma that interacts with the electromagnetic field. While it is common to ignore the displacement c…
Riemann Solvers and Alfven Waves in Black Hole Magnetospheres
Brian Punsly, Dinshaw Balsara, Jinho Kim +1
In the magnetosphere of a rotating black hole, an inner Alfven critical surface (IACS) must be crossed by inflowing plasma. Inside the IACS, Alfven waves are inward directed toward…
On the Linear Stability of Sheared and Magnetized Jets Without Current Sheets - Non-Relativistic Case
Jinho Kim, Dinshaw S. Balsara, Maxim Lyutikov +1
In a prior paper (Kim et al. 2015) we considered the linear stability of magnetized jets that carry no net electric current and do not have current sheets. In this paper, in additi…
A Subluminal Relativistic Magnetohydrodynamics Scheme with ADER-WENO Predictor and Multidimensional Riemann Solver-Based Corrector
Dinshaw S. Balsara, Jinho Kim
The relativistic magnetohydrodynamics (RMHD) set of equations has recently seen increased use in astrophysical computations. Even so, RMHD codes remain fragile. The reconstruction…
On the Linear Stability of Magnetized Jets Without Current Sheets: Non-Relativistic Case
Jinho Kim, Dinshaw S. Balsara, Maxim Lyutikov +3
In this paper we consider stability of magnetized jets that carry no net electric current and do not have current sheets (Gourgouliatos et al. 2012). The non-relativistic MHD equat…
Axially symmetric pseudo-Newtonian hydrodynamics code
Jinho Kim, Hee Il Kim, Matthew William Choptuik +1
We develop a numerical hydrodynamics code using a pseudo-Newtonian formulation that uses the weak field approximation for the geometry, and a generalized source term for the Poisso…
Pseudo-Newtonian Models for the Equilibrium Structures of Rotating Relativistic Stars
Jinho Kim, Hee Il Kim, Hyung Mok Lee
We obtain equilibrium solutions for rotating compact stars including the special relativistic effects. The gravity is assumed to be Newtonian, but we used the active mass density,…
