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…

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…

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…
