The mass, angular momentum, and rotational energy lost by the neutron star are determined self-consistently given the thermal properties of the cooling neutron star's atmosphere and the wind's interaction with the surrounding star. The magnetar drives a relativistic magnetized wind into a cavity created by the outgoing SN shock. For high s","authors_text":"(2) Ohio State Univ., (3) Univ. di Firenze), B.D. Metzger (1), E.
