Global anisotropy vs small-scale fluctuation of neutrino flux in supernova explosions
نویسندگان
چکیده
Effects of small-scale fluctuation of neutrino radiation on supernova explosions are examined. We found that there were large differences between the results of globally anisotropic neutrino radiation and those with fluctuation. As the number of modes of fluctuation increased, the shock positions, entropy distributions, and explosion energies approached those of spherical explosion. It was concluded that global anisotropy of the neutrino radiation is the most effective mechanism of increasing the explosion energy when the total neutrino luminosity is given.

متن کاملSensitivity of Core-Collapse Supernovae to Neutrino Luminosity in Cases of Anisotropic Neutrino Radiation
We demonstrate the importance of anisotropic neutrino radiation in the mechanism of corecollapse supernova explosions. Through a new parameter study with a fixed radiation field of neutrinos, we show that global anisotropy of the neutrino radiation is the most effective mechanism of increasing the explosion energy when the total neutrino luminosity is given. We discuss the reason why, and demon...

We review some of the reasons for believing that the generic core-collapse supernova is neutrino-driven, not MHD-jet driven. We include a discussion of the possible role of rotation in supernova blast energetics and morphology, and speculate on the origin of Cas A's and SN1987A's ejecta fields. Two " explosive " phenomena may be associated with most core collapses, the neutrino-driven su-pernov...
