Photospheric Emission in time-dependent simulations | |||||

Abstract |
Photospheric models for GRB prompt emissions require some dissipation mechanism to produce a power-law like spectrum. Several steady-flow simulations with electron heating (see studies by Beloborodov or Giannios etc.) have succeeded to reproduce GRB spectra. To clarify required conditions for making GRB spectra, a cross check by another type of simulations is useful. Here, we introduce our time-dependent simulations taking into account electron heating, electron-photon scattering, adiabatic cooling, and escape of particles, as well as hadronic processes. Differences in results between ours and the previous studies will be discussed. |
