Dynamics of Type-II Supernovae [PDF]
International Astronomical Union Colloquium, 1996 Hydrodynamical simulations of type-II supernovae in one and two dimensions are performed for the revival phase of the delayed shock by neutrino energy deposition. Starting with a post-collapse model of the 1.31 Mʘ iron core of a 15 Mʘ star immediately after the stagnation of the prompt shock about 10 ms after core bounce, the models are followed for ...

Type II supernova diversity [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractIt is now firmly established that at a significant fraction of hydrogen-rich type II supernovae (SNe II) arise from red supergiant progenitors. However, a large diversity of SN properties exist, and it is presently unclear how this can be understood in terms of progenitor differences and pre-SN stellar evolution. In this contribution, I present

An updated Type II supernova Hubble diagram [PDF]
Astronomy & Astrophysics, 2018 We present photometry and spectroscopy of nine Type II-P/L supernovae (SNe) with redshifts in the 0.045 ≲z≲ 0.335 range, with a view to re-examining their utility as distance indicators. Specifically, we apply the expanding photosphere method (EPM) and the standardized candle method (SCM) to each target, and find that both methods yield distances that ...

The Astrophysical Journal Letters, 2023 We report early-time ultraviolet (UV) and optical spectroscopy of the young, nearby Type II supernova (SN) 2022wsp obtained by the Hubble Space Telescope (HST)/STIS at about 10 and 20 days after the explosion.

Nlte-Effects in Supernovae Type II Photospheres [PDF]
Highlights of Astronomy, 1986 AbstractIn order to provide accurate fluxes of supernovae Type II as needed for the application of the Baade-Wesselink method we have constructed spherical model photospheres for these objects under the assumption that hydrogen and helium are in statistical equilibrium.

Multimessenger Diagnostics of the Engine behind Core-collapse Supernovae
The Astrophysical Journal, 2023 Core-collapse supernova explosions play a wide role in astrophysics by producing compact remnants (neutron stars or black holes) and the synthesis and injection of many heavy elements into their host galaxy.
