A thermonuclear supernova interacting with hydrogen- and helium-deficient circumstellar material. SN 2020aeuh as a SN Ia-CSM-C/O?
K. Tsalapatas, J. Sollerman, R. Chiba +20
Identifying the progenitors of thermonuclear supernovae (Type Ia supernovae; SNe Ia) remains a key objective in contemporary astronomy. The rare subclass of SNe Ia that interacts w…

Hydrodynamic Modelling of Early Peaks in Type Ibc Supernovae with Circumstellar Interaction
Ryotaro Chiba, Takashi J. Moriya
Recent high-cadence transient surveys have uncovered a subclass of Type Ibc supernovae (SNe) that exhibit an early, blue peak lasting a few days before the main, radioactively powe…

Inferring CSM Properties of Type II SNe Using a Magnitude-Limited ZTF Sample
K-Ryan Hinds, Daniel Perley, Jesper Sollerman +20
Although all Type II supernovae (SNe) originate from massive stars possessing a hydrogen-rich envelope, their light curve morphology is diverse, reflecting poorly characterised het…
