Time varying Na I D absorption in ILRTs as a probe of circumstellar material
Robert Byrne, Morgan Fraser, Yongzhi Cai +2
Intermediate-Luminosity Red Transients (ILRTs) are a class of observed transient posited to arise from the production of an electron-capture supernova from a super-asymptotic giant…
Low luminosity Type II supernovae -- IV. SN 2020cxd and SN 2021aai, at the edges of the sub-luminous supernovae class
G. Valerin, M. L. Pumo, A. Pastorello +20
Photometric and spectroscopic data for two Low Luminosity Type IIP Supernovae (LL SNe IIP) are presented. SN 2020cxd reaches a peak absolute magnitude = -13.90 0.05 m…
SN 2021csp -- the explosion of a stripped envelope star within a H and He-poor circumstellar medium
Morgan Fraser, Maximilian D. Stritzinger, Sean J. Brennan +48
We present observations of SN 2021csp, a unique supernova (SN) which displays evidence for interaction with H- and He- poor circumstellar material (CSM) at early times. Using high-…
Core-collapse supernova subtypes in luminous infrared galaxies
E. Kankare, A. Efstathiou, R. Kotak +34
We present the discovery and follow-up observations of two CCSNe that occurred in the luminous infrared galaxy (LIRG), NGC3256. The first, SN2018ec, was discovered using the ESO HA…
Luminous Red Nova AT 2019zhd, a new merger in M 31
A. Pastorello, M. Fraser, G. Valerin +20
We present the follow-up campaign of the luminous red nova (LRN) AT~2019zhd, the third event of this class observed in M 31. The object was followed by several sky surveys for abou…
Revisiting the progenitor of the low-luminosity type II-plateau supernova, SN 2008bk
D. O'Neill, R. Kotak, M. Fraser +3
The availability of updated model atmospheres for red supergiants and improvements in single and binary stellar evolution models, as well as previously unpublished data prompted us…
