Optical Observations of Core-Collapse Supernovae
AIP Conference Proceedings, 2001 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

Core-collapse supernovae as cosmic ray sources. [PDF]
Mon Not R Astron Soc, 2018 Core-collapse supernovae produce fast shocks which expand into the dense circumstellar medium (CSM) of the stellar progenitor. Cosmic rays (CRs) accelerated at these shocks can induce the growth of electromagnetic fluctuations in the pre-shock medium.

Core-collapse Supernovae [PDF]
Proceedings of VI European Summer School on Experimental Nuclear Astrophysics — PoS(ENAS 6), 2013 Marking the inevitable death of a massive star, and the birth of a neutron star or black hole, core-collapse supernovae bring together physics at a wide range in spatial scales, from kilometer-sized hydrodynamic motions (growing to gigameter scale) down to femtometer scale nuclear reactions. Carrying 10$$^{51}$$ ergs of kinetic energy and a rich-mix of

Turbulence in core-collapse supernovae [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2018 Multidimensional simulations show that non-radial, turbulent, fluid motion is a fundamental component of the core-collapse supernova (CCSN) explosion mechanism. Neutrino-driven convection, the standing accretion shock instability, and relic-perturbations from advanced stages of nuclear burning can all impact the outcome of core collapse in a ...

Relativistic Jets in Core-collapse Supernovae [PDF]
The Astrophysical Journal Letters, 2019 Abstract After decades of extensive research the mechanism driving core-collapse supernovae (CCSNe) is still unclear. One common mechanism is a neutrino-driven outflow, but others have been proposed. Among those, a long-standing idea is that jets play an important role in supernova (SN) explosions. Gamma-ray bursts (GRBs) that accompany “

Inferring Core-Collapse Supernova Physics with Gravitational Waves [PDF]
, 2012 Stellar collapse and the subsequent development of a core-collapse supernova explosion emit bursts of gravitational waves (GWs) that might be detected by the advanced generation of laser interferometer gravitational-wave observatories such as Advanced ...

Core-Collapse Supernovae at the Threshold [PDF]
International Astronomical Union Colloquium, 2005 SummaryRecent progress in modeling core-collapse supernovae is summarized and set in perspective. Two-dimensional simulations with state-of-the-art treatment of neutrino transport still fail to produce powerful explosions, but evidence is presented that they are very close to a success.

The progenitors of core-collapse supernovae [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We present maps of the nature of single star progenitors of supernovae and their remnants in mass and metallicity space. We find our results are similar to others but we have gone further in varying the amount of mixing and using various mass-loss schemes to see how the maps change.

Bulk neutrinos and core collapse supernovae [PDF]
, 2002 We discuss the phenomenology of neutrino mixing with bulk fermions in the context of supernova physics. The constraints on the parameter space following from the usual energy loss argument can be relaxed by four orders of magnitude due to a feedback ...
