In accreting binary neutron star systems matter is channelled by the strong magnetic field to the poles of the neutron star. The accreted matter accumulates at the poles to form accretion mounds. Pressure from the confined matter can significantly distort the local magnetic field structure, affecting the X-ray observations and long term evolution of the magnetic field. I will present our recent results on modelling such accretion mounds and MHD simulations performed to study the presence of MHD instabilities in such systems. I will discuss how such instabilities may affect the evolution of the local magnetic field and leave its imprint on X-ray observations in the form of cyclotron resonance scattering features. |
