AbstractWe investigate the magnetic dissipation in the pulsar magnetosphere, in particular, around the Y-point, which is the boundary region between the closed magnetic flux of the dead zone and the open flux in the wind zone, via axisymmetric particle-in-cell (PIC) method in the cylindrical coordinates. We find that magnetic reconnections occur around the Y-point and magnetic islands are repeatedly formed and ejected outward, which suggests that the magnetic energy converts to the kinetic and thermal energy. It is possible that high-energy emission is radiated from this region. It is also possible that the plasma pressure accelerates the pulsar wind. A polar cap radiation may be emitted by falling particles into the neutron star.
