Spectral Dataset of Stripped-Envelope Supernovae from the Tsinghua Supernova Group
Danfeng Xiang, Xiaofeng Wang, Jujia Zhang +40
The extent of envelope stripping in the progenitor stars is directly reflected in the diversity of spectral features observed in stripped-envelope supernovae (SESNe). Through exten…

An investigation on the FWHM of absorption features of type Ia supernovae
Xulin Zhao, Keiichi Maeda, Xiaofeng Wang
We present an investigation of the full width at half maximum (FWHM, or γ) of absorption features of Type Ia supernova (SNe Ia). We found that, the average value of FWHM can be we…

Puzzling High-Velocity Calcium Absorption Features Of Type Ia Supernovae
Xulin Zhao
Absorption features Ca II NIR and Ca II H&K of type Ia supernovae (SNe Ia) are characterized by their strong high-velocity features (HVFs). We find that, for these two features of…
