PROPAGATION OF MAGNETARS THROUGH THE INTERSTELLAR MEDIUM

摘要

We investigate numerically the spinning-down of magnetars rotating at the propeller stage and propagating supersonically through the interstellar medium. Fast moving magnetars lose angular momentum due to direct interaction of the rotating magnetospheres with the non-rotating interstellar medium. Simulations have shown that magnetars spin-down very fast due to such interaction, much faster compared to non-moving ones.
