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,…
Derivative Spectroscopy and its Application at Detecting the Weak Emission/Absorption Lines
Lihuan Yu, Jiangdan Li, Jinliang Wang +4
The development of spectroscopic survey telescopes like Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Apache Point Observatory Galactic Evolution Experiment a…
