Mapping 3-D Explosive Nucleosynthesis in Type II Supernova 2024ggi with Infrared Emission Lines
W. V. Jacobson-Galán, L. Dessart, D. Vartanyan
We present analysis and modeling of optical and infrared (IR) spectroscopy of the Type II supernova (SN II) 2024ggi obtained with ground-based instruments and the James Webb Space…
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 interacts wi…
Relative frequencies of core-collapse supernovae as a function of metallicity: observations vs theoretical predictions
Claudia P. Gutiérrez, LluÃs Galbany, Joseph P. Anderson +4
Understanding supernova (SN) progenitors remains a major challenge in astrophysics, as it involves untangling the complex interplay between stellar physics (e.g., evolution, binari…
SN 2024iss: A Multi-Wavelength Exposé of a Type IIb Supernova with an Early-Time Ultraviolet Spectrum and Shock Breakout Constraints
Rujula Yete, Wynn Jacobson-Galan, Ferdinand Ferdinand +49
We present multi-wavelength observations and a comprehensive analysis of the nearby (D14 Mpc) Type IIb supernova (SN IIb) 2024iss. Observations of SN2024iss include an early…
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…
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…
