Biermann Mechanism in Primordial Supernova Remnant and Seed Magnetic Fields [PDF]

open access: yes, 2005
We study generation of magnetic fields by the Biermann mechanism in the pair-instability supernovae explosions of first stars. The Biermann mechanism produces magnetic fields in the shocked region between the bubble and interstellar medium (ISM), even if
