Understanding Core-Collapse Supernovae
At the University of Arizona, we have a major effort to study core-collapse supernovae, neutrino opacities and transfer, multi-dimensional radiation hydrodynamics, pulsar kicks, and gravitational radiation from supernovae. We have developed a precision 1D (spherical) multigroup implicit Boltzmann solver, SESAME 1 [1, 2], using the Feautrier technique, with the tangent-ray method to achieve exce...
متن کاملProgenitors of core-collapse supernovae
Knowledge of the progenitors of core-collapse supernovae is a fundamental component in understanding the explosions. The recent progress in finding such stars is reviewed. The minimum initial mass that can produce a supernova has converged to 8± 1M⊙, from direct detections of red supergiant progenitors of II-P SNe and the most massive white dwarf progenitors, although this value is model depend...
متن کاملSpectropolarimetry of Core-Collapse Supernovae
We briefly review the young field of spectropolarimetry of corecollapse supernovae (SNe). Spectropolarimetry provides the only direct known probe of early-time supernova (SN) geometry. The fundamental result is that asphericity is a ubiquitous feature of young core-collapse SNe. However, the nature and degree of the asphericity vary considerably. The best predictor of core-collapse SN polarizat...
متن کاملNon - spherical core collapse supernovae
Two-dimensional simulations of strongly anisotropic supernova explosions of a nonrotating 15 M ⊙ blue supergiant progenitor are presented, which follow the hydrodynamic evolution from times shortly after shock formation until hours later. It is shown that explosions which around the time of shock revival are dominated by low-order unstable modes (i.e. by a superposition of the l = 2 and l = 1 m...
متن کاملNucleosynthesis in Core Collapse Supernovae
We present the basic properties of the yields of our latest set of presupernova evolution and explosive nucleosynthesis of massive stars in the range between 11 and 120 M having solar and zero metallicity.
