Nested, asymmetric H-He circumstellar shells in the Type Icn/Ibn SN 2024abvb
The INTEL Collaboration, J. P. Anderson, C. Aster +17
Interacting transients probe mass loss in the final stages of stellar evolution; however, the geometry and timing of multi-episode mass loss remain poorly constrained. SN 2024abvb…
The hydrogen-free circumstellar interaction in the Type Ib supernova 2021efd: A clue to the mechanism of the helium-layer stripping
N. Pyykkinen, T. Nagao, H. Kuncarayakti +27
Stripped-envelope supernovae (SESNe), including Type IIb, Ib, and Ic supernovae (SNe), originate from the explosions of massive stars whose outer envelopes have been largely remove…
Giant outbursts of clumpy material preceding Type II supernova 2024qiw
T. Nagao, H. Kuncarayakti, K. Maeda +6
Observations of core-collapse supernovae suggest that some massive stars undergo intense mass loss shortly before explosion, but the underlying mechanisms remain unknown. Here we r…
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…
Analytical modeling of polarization signals arising from confined circumstellar material in Type II supernovae
T. Nagao, K. Maeda, T. Matsumoto
Recent observations of Type II supernovae (SNe) have brought a challenge in our understanding on the final evolutionary stage of massive stars. The early-time spectra and light cur…
The nebular phase of SN 2024ggi: a low-mass progenitor with no signs of interaction
L. Ferrari, G. Folatelli, K. Ertini +14
Context: SN 2024ggi is a Type II supernova (SN) discovered in the nearby galaxy NGC 3621 (D Mpc) on 2024 April 03.21 UT. Its proximity enabled a detailed investi…
The broad-lined Type-Ic supernova SN 2022xxf with extraordinary two-humped light curves
H. Kuncarayakti, J. Sollerman, L. Izzo +60
We report on our study of supernova (SN) 2022xxf based on observations obtained during the first four months of its evolution. The light curves (LCs) display two humps of similar m…
