Physical mechanism of core-collapse supernovae that neutrinos drive [PDF]

Proceedings of the Japan Academy. Series B, Physical and Biological Sciences
The current understanding of the mechanism of core-collapse supernovae (CCSNe), one of the most energetic events in the universe associated with the death of massive stars and the main formation channel of compact objects such as neutron stars and black ...

Parameters of core-collapse [PDF]

Monthly Notices of the Royal Astronomical Society, 2003
This paper considers the phenomenon of deep core collapse in collisional stellar systems, with stars of equal mass. The collapse takes place on some multiple, $\xi ^{-1}$, of the central relaxation time, and produces a density profile in which $\rho ...

Core-Collapse Supernovae: Reflections and Directions [PDF]

Progress of Theoretical and Experimental Physics, 2012
Core-collapse supernovae are among the most fascinating phenomena in astrophysics and provide a formidable challenge for theoretical investigation. They mark the spectacular end of the lives of massive stars and, in an explosive eruption, release as much

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.

3-Dimensional Core-Collapse

, 2003
In this paper, we present the results of 3-dimensional collapse simulations of rotating stars for a range of stellar progenitors. We find that for the fastest spinning stars, rotation does indeed modify the convection above the proto-neutron star, but it

Core-Collapse Simulations of Rotating Stars [PDF]

The Astrophysical Journal, 1999
We present the results from a series of two-dimensional core-collapse simulations using a rotating progenitor star. We find that the convection in these simulations is less vigorous because a) rotation weakens the core bounce which seeds the neutrino ...

Explosion Mechanisms of Core-Collapse Supernovae [PDF]

Annual Review of Nuclear and Particle Science, 2012
Supernova theory, numerical and analytic, has made remarkable progress in the past decade. This progress was made possible by more sophisticated simulation tools, especially for neutrino transport, improved microphysics, and deeper insights into the role

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.

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.

Core Collapse via Coarse Dynamic Renormalization

Physical Review Letters, 2005
In the context of the recently developed "equation-free" approach to computer-assisted analysis of complex systems, we extract the self-similar solution describing core collapse of a stellar system from numerical experiments.
