SN 2025aico: Early observations of a faint Type IIb supernova with a low-mass envelope

J. -W. Zhao, A. Pastorello, B. Kumar +45

We aimed to investigate the physical properties and the underlying explosion mechanisms of the Type IIb SN 2025aico. Through a comprehensive analysis of early-phase optical light c…

The undetectable fraction of core-collapse supernovae in luminous infrared galaxies -- II. GSAOI/GeMS dataset

I. Mäntynen, E. Kankare, S. Mattila +7

Core-collapse supernovae (CCSNe) in luminous infrared galaxies (LIRGs) can have extreme line-of-sight host galaxy dust extinctions, which leads to a large fraction of the events re…

AT 2025abao: The fourth luminous red nova in M 31

A. Reguitti, A. Pastorello, G. Valerin +15

We present photometric and spectroscopic observations of the luminous red nova (LRN) AT 2025abao, the fourth discovered in M 31. The LRN, associated to the asymptotic giant branch…

SN 2022ngb: A faint, slowly evolving Type IIb supernova with a low-mass envelope

J. -W. Zhao, S. Benetti, Y. -Z. Cai +35

An extensive photometric and spectroscopic follow-up campaign of the Type IIb SN 2022ngb is presented in the article. Through detailed modeling of this dataset, we aim to constrain…

Massive stars exploding in a He-rich circumstellar medium XII. SN 2024acyl: A fast, linearly declining Type Ibn supernova with early flash-ionisation features

Y. -Z. Cai, A. Pastorello, K. Maeda +63

We present a photometric and spectroscopic analysis of the Type Ibn supernova (SN) 2024acyl. It rises to an absolute magnitude peak of about -17.58 mag in 10.6 days, and displays a…

Long-term evolution of the SN 2009ip-like transient SN 2016cvk

K. Matilainen, E. Kankare, S. Mattila +21

The interacting transient SN 2016cvk (ASASSN-16jt) is a member of the peculiar SN 2009ip-like events. We present our follow-up data and aim to draw conclusions about the physical n…

Explosion sites of SN 1994W-like transients

E. Kankare, T. Kangas, M. Fraser +8

We study a sample of narrow-line transients that share characteristics with the Type IIn classified supernova (SN) 1994W, a prototypical member of this class of events, via investi…

Advancing accuracy in age determinations of old-disk stars using an oscillating red giant in an eclipsing binary

J. S. Thomsen, A. Miglio, K. Brogaard +26

The study of resonant oscillation modes in low-mass red giant branch stars enables their ages to be inferred with exceptional (10%) precision, unlocking the possibility to re…

Observations of the luminous red nova AT 2021biy in the nearby galaxy NGC 4631

Y. -Z. Cai, A. Pastorello, M. Fraser +73

We present an observational study of the luminous red nova (LRN) AT\,2021biy in the nearby galaxy NGC\,4631. The field of the object was routinely imaged during the pre-eruptive st…

Panchromatic evolution of three luminous red novae: Forbidden hugs in pandemic times -- IV

A. Pastorello, G. Valerin, M. Fraser +77

We present photometric and spectroscopic data on three extragalactic luminous red novae (LRNe): AT2018bwo, AT2021afy, and AT2021blu. AT2018bwo was discovered in NGC45 (at 6.8 Mpc)…
