Signatures of the Shock Interaction as an Additional Power Source in the Nebular Spectra of SN 2023ixf
Amit Kumar, Raya Dastidar, Justyn R. Maund +2
Red supergiants may lose significant mass during the final 100-1000 years before core collapse, shaping their circumstellar environment. The supernova (SN) shockwave propagating th…
A statistical study of the metallicity of core-collapse supernovae based on VLT/MUSE integral-field-unit spectroscopy
Qiang Xi, Ning-Chen Sun, Yi-Han Zhao +4
Metallicity plays a crucial role in the evolution of massive stars and their final core-collapse supernova (CCSN) explosions. Integral-field-unit (IFU) spectroscopy can provide a s…
Constraining the progenitor of the nearby Type II-P SN 2024ggi with environmental analysis
Xinyi Hong, Ning-Chen Sun, Zexi Niu +3
The progenitors of Type II-P supernovae (SN) have been confirmed to be red supergiants. However, the upper mass limit of the directly probed progenitors is much lower than that pre…
Exclusion of a direct progenitor detection for the Type Ic SN 2017ein based on late-time observations
Yi-Han Zhao, Ning-Chen Sun, Junjie Wu +7
To date, SN 2017ein is the only Type Ic supernova with a directly identified progenitor candidate. This candidate points to a very massive (45 ) Wolf-Rayet progenitor,…
Discovery of a dusty yellow supergiant progenitor for the Type IIb SN 2017gkk
Zexi Niu, Ning-Chen Sun, Jifeng Liu
Type IIb supernovae are important subclass of stripped-envelope supernovae (SNe), which show H lines only at early times. Their progenitors are believed to contain a low-mass H env…
The disappearance of the blue and luminous progenitor of the Type IIn SN 2010jl
Zexi Niu, Ning-Chen Sun, Jifeng Liu
Type IIn supernovae (SNe) exhibit narrow hydrogen lines that arise from the strong interaction between ejecta and circumstellar material. It remains poorly understood, however, wha…
