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

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 Type II-P Supernova 2019mhm and Constraints on its Progenitor System
The Astrophysical Journal, 2023 We present pre- and postexplosion observations of the Type II-P supernova (SN II-P) 2019mhm located in NGC 6753. Based on optical spectroscopy and photometry, we show that SN 2019mhm exhibits broad lines of hydrogen with a velocity of −8500 ± 200 km s ...

Black Hole Formation Accompanied by the Supernova Explosion of a 40 M ⊙ Progenitor Star
The Astrophysical Journal, 2023 We have simulated the collapse and evolution of the core of a solar-metallicity 40 M _⊙ star and find that it explodes vigorously by the neutrino mechanism, despite its very high “compactness.” Within ∼1.5 s of explosion, a black hole forms.

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.

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 ...

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.

The Astrophysical Journal, 1991 Stars clusters undergo core collapse on a thermal time scale. This results follows from a detailed simulations in the form of N-body, Fokker-Planck, and gas sphere models. The shrinking of the core, both in size as well as mass, is often heuristically attributed to the negative heat capacity of gravity, as follows from the virial theorem. However, this
