The mechanism(s) of core-collapse supernovae [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2017 Core-collapse supernovae (CCSNe) are the explosions that attend the deaths of massive stars. Despite decades of research, several aspects of the mechanism that drives these explosions remain uncertain and the subjects of continued investigation. In this short review, I will give an overview of the CCSN mechanism and current research in the field.

Progenitors of Core-Collapse Supernovae [PDF]
Annual Review of Astronomy and Astrophysics, 2009 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 (SN) has converged to 8 ± 1 M⊙from direct detections of red supergiant progenitors of II-P SNe and the most massive white dwarf ...

Turbulence in Core-collapse Supernovae
The Astrophysical JournalIt is understood in a general sense that turbulent fluid motion below the shock front in a core-collapse supernova stiffens the effective equation of state of the fluid and aids in the revival of the explosion.

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.

On the progenitors of core-collapse supernovae [PDF]
Astrophysics and Space Science, 2010 Theory holds that a star born with an initial mass between about 8 and 140 times the mass of the Sun will end its life through the catastrophic gravitational collapse of its iron core to a neutron star or black hole. This core collapse process is thought to usually be accompanied by the ejection of the star's envelope as a supernova.

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.

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.

Revealing the Progenitor of SN 2021zby through Analysis of the TESS Shock-cooling Light Curve
The Astrophysical Journal Letters, 2023 We present early observations and analysis of the double-peaked Type IIb supernova (SN IIb) SN 2021zby. TESS captured the prominent early shock-cooling peak of SN 2021zby within the first ∼10 days after explosion with a 30 minute cadence.

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 ...
