A phase-dependent view of cyclotron lines from model accretion mounds on neutron stars

Mukherjee, Dipanjan; Bhattacharya, Dipankar

Description

In this paper we make a phase-dependent study of the effect of the distortion of the local magnetic field due to confinement of the accreted matter in X-ray pulsars on the cyclotron spectra emitted from the hotspot. We have numerically solved the Grad–Shafranov equation for axisymmetric static magnetohydrodynamic (MHD) equilibria of the matter confined at the polar cap of neutron stars. From our solution, we model the cyclotron spectra that will be emitted from the region, using a simple...[Show more]
