SN 2024abvb: a Type Ibn/Icn supernova with evidence of helium and an extreme offset from its host galaxy

Callum Aster, Cosimo Inserra, Andrea Pastorello +27

We present spectroscopic and photometric observations and analysis of SN 2024abvb, a peculiar transitional Type Ibn/Icn supernova located at an unusually large projected distance f…

Nothing to see here: Failed supernovae are faint or rare

Robert Byrne, Morgan Fraser

The absence of Type IIP core-collapse supernovae arising from progenitors above 17 solar masses suggests the existence of another evolutionary path by which massive stars end their…

The luminous red nova variety: AT 2020hat and AT 2020kog

A. Pastorello, G. Valerin, M. Fraser +32

We present the results of our monitoring campaigns of the luminous red novae (LRNe) AT 2020hat in NGC 5068 and AT 2020kog in NGC 6106. The two objects were imaged (and detected) be…

A luminous stellar outburst during a long-lasting eruptive phase first, and then SN IIn 2018cnf

A. Pastorello, A. Reguitti, A. Morales-Garoffolo +45

We present the results of the monitoring campaign of the Type IIn supernova (SN) 2018cnf (aka ASASSN-18mr). It was discovered about 10 days before the maximum light (on MJD = 58293…

Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm

G. Terreran, M. L. Pumo, T. -W. Chen +41

We present our study of OGLE-2014-SN-073, one of the brightest Type II SN ever discovered, with an unusually broad lightcurve combined with high ejecta velocities. From our hydrody…

Core-collapse supernova progenitor constraints using the spatial distributions of massive stars in local galaxies

T. Kangas, L. Portinari, S. Mattila +7

We study the spatial correlations between the H emission and different types of massive stars in two local galaxies, the Large Magellanic Cloud (LMC) and Messier 33. We compare…
