abstract
I use photometry and spectroscopy data for 24 Type II plateau supernovae to examine their observed and physical properties. This dataset shows that these objects encompass a wide range in their observed properties (plateau luminosities, tail luminosities, and expansion velocities) and their physical parameters (explosion energies, ejected masses, initial radii, and 56Ni yields). Several regularities emerge within this diversity, which reveal (1) a continuum in the properties of Type II plateau supernovae, (2) a one parameter family (at least to first order), (3) evidence that stellar mass plays a central role in the physics of core collapse and the fate of massive stars.

Exploring the effect of mixing in Low-Luminosity Type IIp Supernovae by modeling SN 2024abfl
Disabling RTI and boxcar mixing in MESA+STELLA models of a 10 M⊙ progenitor reproduces SN 2024abfl’s flat plateau and steep post-plateau drop using previously proposed mass, radius, and energy.
