Ideal MHD instabilities for coronal mass ejections
Rony Keppens, Yang Guo, Kirit Makwana +4
We review and discuss insights on ideal magnetohydrodynamic (MHD) instabilities that can play a role in destabilizing solar coronal flux rope structures. For single flux ropes, fai…
Multi-layered Kelvin-Helmholtz Instability in the Solar Corona
Ding Yuan, Yuandeng Shen, Yu Liu +2
The Kelvin-Helmholtz (KH) instability is commonly found in many astrophysical, laboratory, and space plasmas. It could mix plasma components of different properties and convert dyn…
General relativistic resistive magnetohydrodynamics with robust primitive variable recovery for accretion disk simulations
Bart Ripperda, Fabio Bacchini, Oliver Porth +6
Recent advances in black hole astrophysics, particularly the first visual evidence of a supermassive black hole at the center of the galaxy M87 by the Event Horizon Telescope (EHT)…
Forward Modeling of SDO/AIA and X-Ray Emission from a Simulated Flux Rope Ejection
Xiaozhou Zhao, Chun Xia, Tom Van Doorsselaere +2
We conduct forward-modeling analysis based on our 2.5 dimensional magnetohydrodynamics (MHD) simulation of magnetic flux rope (MFR) formation and eruption driven by photospheric co…
A geometric multigrid library for quadtree/octree AMR grids coupled to MPI-AMRVAC
Jannis Teunissen, Rony Keppens
We present an efficient MPI-parallel geometric multigrid library for quadtree (2D) or octree (3D) grids with adaptive refinement. Cartesian 2D/3D and cylindrical 2D geometries are…
