Plastic damping of Alfven waves in magnetar flares and delayed afterglow emission.


Abstract (from CDS):

Magnetar flares generate Alfvén waves bouncing in the closed magnetosphere with energy up to ∼ 1046 erg. We show that on a timescale of 10 ms the waves are transmitted into the star and form a compressed packet of high energy density. This packet strongly shears the stellar crust and initiates a plastic flow, heating the crust and melting it hundreds of meters below the surface. A fraction of the deposited plastic heat is eventually conducted to the stellar surface, contributing to the surface afterglow months to years after the flare. A large fraction of heat is lost to neutrino emission or conducted into the core of the neutron star.
