Magnetorotational Explosions of Core-Collapse Supernovae
Acta Polytechnica CTU Proceedings, 2014 Core-collapse supernovae are accompanied by formation of neutron stars. The gravitation energy is transformed into the energy of the explosion, observed as SN II, SN Ib,c type supernovae.

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

Magnetorotational Instability in Core-Collapse Supernovae [PDF]
Acta Physica Polonica B Proceedings Supplement, 2017 We discuss the relevance of the magnetorotational instability (MRI) in core-collapse supernovae (CCSNe). Our recent numerical studies show that in CCSNe, the MRI is terminated by parasitic instabilities of the Kelvin-Helmholtz type.

Progenitors of Core-Collapse Supernovae [PDF]
Proceedings of the International Astronomical Union, 2017 Massive stars have a strong impact on their surroundings, in particular when they produce a core-collapse supernova at the end of their evolution. In these proceedings, we review the general evolution of massive stars and their properties at collapse as ...

Gravitational Waves from Core Collapse Supernovae [PDF]
Classical and Quantum Gravity, 2010 We present the gravitational wave signatures for a suite of axisymmetric core collapse supernova models with progenitors masses between 12 and 25 solar masses.

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 ...

Theory of core-collapse supernovae [PDF]
Physics Reports, 2007 Advances in our understanding and the modeling of stellar core-collapse and supernova explosions over the past 15 years are reviewed, concentrating on the evolution of hydrodynamical simulations, the description of weak interactions and nuclear equation of state effects, and new insights into the nucleosynthesis occurring in the early phases of the ...
