Neutron star-companion interaction in core collapse supernovae. Population synthesis based on detailed binary evolution models
Andrea Ercolino, Norbert Langer, Avishay Gal-Yam +6
Most massive stars live in binary systems. When the first supernova (SN) in a binary occurs, the ejecta hit the companion, which may inflate as a consequence, and then interact wit…
An optical to infrared study of type II SN2024ggi at nebular times
Luc Dessart, Rubina Kotak, Wynn Jacobson-Galan +5
We present 0.3-21mic observations at ~275d and ~400d for Type II supernova (SN) 2024ggi, combining ground-based optical and near-infrared data from the Keck I/II telescopes and spa…
Very Late-Time JWST and Keck Spectra of the Oxygen-Rich Supernova 1995N
Geoffrey C. Clayton, R. Wesson, Ori D. Fox +43
We present new {\it JWST}/MIRI MRS and Keck spectra of SN 1995N obtained in 2022--2023, more than 10,000 days after the supernova (SN) explosion. These spectra are among the latest…
Two Decades of Dust Evolution in SN 2005af through JWST, Spitzer, and Chemical Modeling
Arkaprabha Sarangi, Szanna Zsiros, Tamas Szalai +20
The evolution of dust in core-collapse supernovae (SNe), in general, is poorly constrained owing to a lack of infrared observations after a few years from explosion. Most theories…
JWST/MIRI detects the dusty SN1993J about 30 years after explosion
Tamás Szalai, Szanna Zsíros, Jacob Jencson +37
Core-collapse supernovae (CCSNe) have long been considered to contribute significantly to the cosmic dust budget. New dust cools quickly and is therefore detectable at mid-infrared…
Using CSST and ejecta-wind interaction in type II-P supernovae to constrain the wind-mass loss of red supergiant stars
Jingxiao Luo, Luc Dessart, Xuefei Chen +1
The properties of H-rich, type II-plateau supernova (SN II-P) progenitors remain uncertain, and this is primarily due to the complexities associated with red supergiant (RSG) wind-…
A sequence of Type Ib, IIb, II-L, and II-P supernovae from binary-star progenitors of varying initial separation
Luc Dessart, Claudia P. Gutierrez, Andrea Ercolino +2
Over the last decade, evidence has accumulated that massive stars do not typically evolve in isolation but instead follow a tumultuous journey with a companion star on their way to…
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…
