論文摘要

Magnetar-powered Supernovae

[ Oral ]

Ke-Jung (Ken) Chen, ASIAA/NAOJ

Massive stars of 30 - 80 solar masses eventually collapse to black holes because the neutrino energy cannot drive a strong shock to overcome the ram pressure of infall, so core bounce fails to produce an explosion. But this picture can change with rapidly rotating stars, in which a neutron star (NS) with a period of a few milliseconds may be born. Rotation can amplify the magnetic field of the NS above 1E15 G, creating a magnetar. In this talk, I discuss about the theoretical models of the exotic explosions powered by the magnetars, and their astrophysical applications.
