【 摘 要 】

We have studied shock in magnetized accretion flow/funnel flow in case of neutron star with bremsstrahlung cooling and cyclotron cooling. All accretion solutions terminate with a shock close to the neutron star surface, but at some regions of the parameter space, it also harbours a second shock away from thestar surface.We have found that cyclotron cooling is necessary for correct accretion solutions which match the surface boundary conditions.
