Early-phase Simultaneous Multiband Observations of the Type II Supernova SN 2024ggi with Mephisto
The Astrophysical Journal LettersWe present early-phase good-cadence (hour-to-day) simultaneous multiband ( ugi and vrz bands) imaging of the nearby supernova SN 2024ggi, which exploded in the nearby galaxy NGC 3621.

The Astrophysical JournalWe present a comprehensive analysis of 32 type II supernovae (SNe II) with plateau phase photometry and late phase ( nebular ) spectroscopy available, aiming to bridge the gap between the surface and core of their red supergiant (RSG) progenitors.

The quiescent progenitors of four Type II-P/L supernovae [PDF]
, 2018 We present Large Binocular Telescope difference imaging data for the final years of four Type II-P/L supernovae progenitors. For all four, we find no significant evidence for stochastic or steady variability in the U, B, V, or R bands.

Progenitor stars of type IIn supernovae using the NCR method [PDF]
Supernovae are massive stars exploding at the end of their lifetime, when the processes active during their life can no longer maintain a stable star. There are multiple ways for a star to become a supernova, and thus they are classified through their ...

Evidence is briefly reviewed for believing that the core bounce mechanism actually gives rise to Type II supernovae in massive stars. Strongest evidence comes from the historical observation of the Crab Nebula light curve, the existence of pulsars, and from the nucleosynthesis of a few very neutron-rich isotopes such as 48Ca.

Models of Type II Supernovae and Supernova 1987A
1989Implications from the observations of SN 1987A for the standard model of type II supernova explosions are discussed. In particular, we find evidence for strong mixing prior to the explosion of SN 1987A, which was not expected from simple spherically symmetric models.
