Magnetic field structure in accretion columns on HMXB and effects on CRSF
Dipanjan Mukherjee, Dipankar Bhattacharya, Andrea Mignone
In accreting neutron star binaries, matter is channelled by the magnetic fields from the accretion disc to the poles of neutron stars forming an accretion mound. We model such moun…
MHD instabilities in accretion mounds - II. 3D simulations
Dipanjan Mukherjee, Dipankar Bhattacharya, Andrea Mignone
We investigate the onset of pressure driven toroidal mode instabilities in accretion mounds on neutron stars by 3D MHD simulations using the PLUTO MHD code. Our results confirm tha…
MHD instabilities in accretion mounds on neutron star binaries
Dipanjan Mukherjee, Dipankar Bhattacharya, Andrea Mignone
We have numerically solved the Grad-Shafranov equation for axisymmetric static MHD equilibria of matter confined at the polar cap of neutron stars. From the equilibrium solutions w…
