Final Moments III: Explosion Properties and Progenitor Constraints of CSM-Interacting Type II Supernovae
W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52
We present analysis of the plateau and late-time phase properties of a sample of 39 Type II supernovae (SNe II) that show narrow, transient, high-ionization emission lines (i.e., "…

Observational diversity of bright long-lived Type II supernovae
T. Nagao, T. M. Reynolds, H. Kuncarayakti +21
In various types of supernovae (SNe), strong interaction between the SN ejecta and circumstellar material (CSM) has been reported. This raises questions on their progenitors and ma…
