Parameter space study of magnetohydrodynamic flows around magnetized compact objects

摘要

We solve the magnetohydrodynamic (MHD) equations governing axisymmetric flowsaround neutron stars and black holes and found all possible solution topologiesfor adiabatic accretion. We divide the parameter space spanned by the conservedenergy and angular momentum of the flow in terms of the flow topologies. Wealso study the possibility of the formation of the MHD shock waves.
