SN 2020bij and four other Type IIP SNe with slow-rising light curves and high velocities are modeled with weak to no CSM interaction, suggesting a new subclass linked to confined CSM.

The DECam Shadow Survey has detected variable LBV eruptions in AT2017des with peaks brightening by ~0.05 mag per year, reaching luminosities similar to extreme SN impostors.
SN 2020aze displays early He II emission from ejecta-CSM interaction, a steep V-band decline, and semi-analytical modeling yields a ~14 solar-mass red supergiant progenitor with ~12 solar-mass ejecta and 1.5e51 erg explosion energy.
Eruptive mass loss in red supergiants increases linearly with metallicity, calibrated via by-eye fits to Local Group luminosity functions, preventing initial masses above about 20 solar masses from reaching the red supergiant phase.

Calibrating Eruptive Mass Loss in Red Supergiants with Local Group Data
Eruptive mass loss in red supergiants increases linearly with metallicity, calibrated via by-eye fits to Local Group luminosity functions, preventing initial masses above about 20 solar masses from reaching the red supergiant phase.
