[32.11] Intense Magnetism in Supernovae

C. Thompson (Canadian Institute for Theoretical Astrophysics)

Observations of the Soft Gamma Repeaters and Anomalous X-ray Pulsars have provided strong evidence for a class of neutron stars with magnetic fields exceeding 1015 G. This talk will overview the excellent prospects for generating such intense fields in a core-collapse supernova, with a focus on the violent convective motions believed to occur both inside and outside the neutrinosphere of the forming neutron star. I will also examine the effects of late fallback, and the role of (electron-type) neutrinos in aiding buoyant motions of the magnetic field. The case will be made that the SGRs and AXPs are distinguished from classical radio pulsars by a very rapid initial rotation of the neutron star.
