VENUS: an ultra-faint galaxy hosting the metal-poor type II supernova at Witnessing the initial metal enrichment with extremely frequent core-collapse supernovae?
Yoshihisa Asada, Seiji Fujimoto, Joseph F. V. Allingham +50
We present the first characterization of the host galaxy of a recently discovered type IIP SN at (SN Eos). SN Eos and its host galaxy are gravitationally lensed and multip…
JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova
Colin W. Macrie, Conor Larison, Huei Sears +43
We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from 2 weeks before to 1 year after maximum light. JWST near- and mid-infrared sp…
Single vs. Binary Origin: The Diversity of Stripped-Envelope Supernova Remnants
Gaku Kawashima, Shiu-Hang Lee, Keiichi Maeda +1
Core-collapse supernova remnants (CCSNRs) are crucial for understanding the final stages of massive star evolution, as they reflect the imprints of their progenitors' pre-explosion…
Revisiting the Suzaku spectrum of the Galactic SNR W 49 B: non-detection of iron K-shell charge exchange emission and refined ejecta mass ratios of iron-group elements
Makoto Sawada, Toshiki Sato, Keiichi Maeda +1
The origin of the recombining plasma in several Galactic SNRs has been debated. A plausible mechanism would be a rapid cooling in the past, either by adiabatic or conductive proces…
A cosmic formation site of silicon and sulphur revealed by a new type of supernova explosion
Steve Schulze, Avishay Gal-Yam, Luc Dessart +47
The cores of stars are the cosmic furnaces where light elements are fused into heavier nuclei. The fusion of hydrogen to helium initially powers all stars. The ashes of the fusion…
Missing Titanium in the Asymmetric Supernova Remnant W49B
Toshiki Sato, Makoto Sawada, Keiichi Maeda +2
The progenitor of the W49B supernova remnant is still under debate. One of the candidates is a jet-driven core-collapse supernova. In such a highly asymmetric explosion, a strong $…
