A gamma-ray burst fireball model via the compression and heating of binary neutron stars

PDF Version Also Available for Download.

Description

A model is proposed for gamma-ray bursts based upon general relativistic hydrodynamic studies of the compression, heating, and collapse of close binary neutron stars as they approach their last stable orbit. Relativistic compression and heating before collapse may produce a neutrino burst of {approx} 10{sup 53} ergs lasting several seconds. The associated thermal neutrino emission produces an e{sup +}e{sup -} pair plasma by {nu}{bar {nu}} annihilation. We present a hydrodynamic simulation of the formation and evolution of the pair plasma associated with the neutrino burst. We find that this pair plasma leads to the production of {approx} 10{sup 51} - ... continued below
