Optical Observations of Core-Collapse Supernovae
I present an overview of optical observations (mostly spectra) of Type II, Ib, and Ic supernovae (SNe). SNe II are defined by the presence of hydrogen, and exhibit a very wide variety of properties. SNe II-L tend to show evidence of late-time interaction with circumstellar material. SNe IIn are distinguished by relatively narrow emission lines with little or no P-Cygni absorption component and ...
متن کاملUnderstanding 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 کاملEstimating the Explosion Time of Core-collapse Supernovae from Their Optical Light Curves
Core-collapse supernovae are among the prime candidate sources of high energy neutrinos and gravity waves. The detection prospects for neutrinos and gravity waves can be greatly enhanced through cross-correlation with the well established optical photon signal. The significance of the correlation improves with the resolution on the supernova explosion time determined from the optical data. We p...
