    Abstract

    We carry out series of numerical simulations on the magnetorotational supernovae in order to study about recoil of so-called "magnetars", highly magnetized slowly rotating neutron stars. We assume that the core initially rotates rapidly and is strongly magnetized. Presumed initial magnetic fields have dipole-like configurations somewhat offset from the center of the cores. As a result, equatorially asymmetric supernova explosions are produced and recoil velocities of ∼500-1000kms-1 are obtained which suggest that magnetars possibly have large recoil velocities as ordinary pulsars.
