2 Jun 2020 | Abstract: | Time-dependent electromagnetic signatures from core-collapse supernovae are
the result of detailed transport of the shock-deposited and
radioactively-powered radiation through the stellar ejecta. Due to the
complexity of the underlying radiative processes, considerable approximations
are made to simplify key aspects of the radiation transport problem. We present
a systematic comparison of the moment-based radiation hydrodynamical code
STELLA and the Monte Carlo radiation transport code Sedona in the 1D modeling
of Type II-Plateau supernovae. Based on explosion models generated from the
Modules for Experiments in Stellar Astrophysics (MESA) instrument, we find
remarkable agreements in the modeled light curves and the ejecta structure
thermal evolution, affirming the fidelity of both radiation transport modeling
approaches. The radiative moments computed directly by the Monte Carlo scheme
in Sedona also verify the accuracy of the moment-based scheme. We find that the
coarse resolutions of the opacity tables and the numerical approximations in
STELLA have insignificant impact on the resulting bolometric light curves,
making it an efficient tool for the specific task of optical light curve
modeling. | Source: | arXiv, 2006.1832 | Services: | Forum | Review | PDF | Favorites |
