Investigating field burial by magnetically confined accretion mounds on Neutron Stars
Saurabh Yeole, Dipanjan Mukherjee, Ankush Mandal
We explore the problem of magnetic confinement of accreted matter forming an accretion mound near the magnetic poles of a neutron star. We calculate the magnetic field geometry of…
