Doppler-shifted Signatures in the Chromospheric Line Profiles of II Pegasi
The Astrophysical JournalStellar flares are frequently accompanied by prominence eruptions, coronal mass ejections (CMEs), and other forms of plasma motion. Based on the long-term high-resolution spectroscopic monitoring data set of the RS CVn-type star II Pegasi (II Peg), we ...

Further Investigation on Chromospheric Activity Patterns of the RS Canum Venaticorum Star V711 Tauri
The Astronomical JournalWe present new long-term spectroscopic observations of the very active RS Canum Venaticorum (RS CVn) star V711 Tauri (V711 Tau), obtained during several observing runs from 2005 to 2021.

The Astrophysical Journal Supplement SeriesAbstract Accurately characterizing the intrinsic stellar photometric noise induced by stellar astrophysics, such as stellar activity, granulation, and oscillations, is of crucial importance for detecting transiting exoplanets. In this study, we investigate the relation between the intrinsic stellar photometric noise, quantified by the ...
