Binary Interaction Can Yield a Diversity of Circumstellar Media around Type II Supernova Progenitors
Recent observations of supernovae (SNe) have indicated that a fraction of massive stars possess dense circumstellar medium (CSM) at the moment of their core collapses.

Magnetorotational Explosions of Core-Collapse Supernovae
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.

Models of Type II Supernova Explosions [PDF]
Present stellar evolution codes predict that stars with He-core masses above approximately 2 M⊙, corresponding to main sequence masses of at least 8 M⊙ burn carbon non-violently. After hydrostatic core carbon burning all those stars contain O-Ne-Mg cores but their further evolution is strongly dependent on the stellar entropy and thus on the main ...

Type II supernovae at high redshifts
A hydro code coupled with radiation transfer was applied to produce monochromatic light curves of two models of type II supernovae (SN II) simulating SN II-P and SN IIb (SN 1993J-like). We then used these template light curves to evaluate the possibility of detecting SNe II at different redshifts.

SN 2021wvw: A Core-collapse Supernova at the Subluminous, Slower, and Shorter End of Type IIPs
We present detailed multiband photometric and spectroscopic observations and analysis of a rare core-collapse supernova, SN 2021wvw, that includes photometric evolution up to 250 days and spectroscopic coverage up to 100 days postexplosion.

Spectral Modeling of Type II Supernovae [PDF]
Using models of the SN~IIP 2005cs, we show that detailed spectral analysis can be used to determine reddening and abundances.

Neutrinos from Type-II Supernovae
Abstract In our work we investigate the stellar surface fluxes of different neutrino flavors, both with and without matter effects, while aiming to consider the varying density of the progenitor star to reveal intriguing variations in their behavior. By examining both normal and inverted neutrino mass hierarchies in studies of neutrino fluxes,
