摘要：
We perform NTHD simulations of a thin resistive and viscous accretion disk around neutron star with the surface dipolar magnetic field of 108 Gauss. The system evolution is followed during the interval of 500 millisecond pulsar rotations. Matter is accreted through a stable accretion column from the disk onto the star. We also show propagation of the stellar wind through the corona. Analysis of the mass accretion flux and torques on the star shows that the disk reaches the quasi-stationary state.
