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

Gravitational waves and core-collapse supernovae [PDF]
, 2017 A mechanism of formation of gravitational waves in the Universe is considered for a nonspherical collapse of matter. Nonspherical collapse results are presented for a uniform spheroid of dust and a finite-entropy spheroid. Numerical simulation results on

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.

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.
