On the Conditions for Neutron-rich Gamma-ray Burst Outflows
We calculate the structure and neutron content of neutrino-heated magnetohydrodynamic winds driven from the surface of newly-formed magnetars (“proto-magnetars”) and from the midplane of hyper-accreting disks, two of the possible central engines for gamma-ray bursts (GRBs) and hyper-energetic supernovae (SNe). Both the surface of proto-magnetars and the midplane of neutrino-cooled accretion flo...
متن کاملGamma-Ray Burst Afterglows
Extended, fading emissions in multi-wavelength are observed following Gamma-ray bursts (GRBs). Recent broadband observational campaigns led by the Swift Observatory reveal rich features of these GRB afterglows. Here we review the latest observational progress and discuss the theoretical implications for understanding the central engine, composition, and geometric configuration of GRB jets, as w...
متن کاملGamma-ray burst models.
I consider various possibilities for making gamma-ray bursts, particularly from close binaries. In addition to the much-studied neutron star+neutron star and black hole+neutron star cases usually considered good candidates for short-duration bursts, there are also other possibilities. In particular, neutron star+massive white dwarf has several desirable features. These systems are likely to pro...
متن کاملGamma-ray Burst Energetics
We estimate the fraction of the total energy in a Gamma-Ray Burst (GRB) that is radiated in photons during the main burst. Random internal collisions among different shells limit the efficiency for converting bulk kinetic energy to photons. About 6% of the energy of explosion is converted to radiation for long duration bursts (lasting 10s or more); the efficiency is significantly smaller for sh...
