Doppler-shifted Signatures in the Chromospheric Line Profiles of II Pegasi
Cao Dongtao, Gu shenghong
Stellar flares are frequently accompanied by prominence eruptions, coronal mass ejections (CMEs), and other forms of plasma motion. Based on the long-term high-resolution spectrosc…
Further Investigation on Chromospheric Activity Patterns of the RS Canum Venaticorum Star V711 Tauri
Cao Dongtao, Gu Shenghong
We 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…
A Possible Stellar CME Event Associated with a Long-duration Optical Flare on the RS CVn-type Star UX Arietis
Cao Dongtao, Gu Shenghong
Coronal mass ejections (CMEs) are large-scale eruptions of magnetized plasma from stellar coronae, and they are always accompanied by flares. In this study, we present high-resolut…
Investigating Possible Stellar Coronal Mass Ejections in M-type Dwarfs Using the CARMENES DR1 Spectra
Cao Dongtao, Gu Shenghong
Stellar coronal mass ejections (CMEs) have significant impacts on surrounding exoplanets and stellar evolution. For M-type dwarf stars, hosting close-in habitable zones, frequent a…
Magnetic activity of ultracool dwarfs in the LAMOST DR11
Yue Xiang, Shenghong Gu, Dongtao Cao
Ultracool dwarfs consist of lowest-mass stars and brown dwarfs. Their interior is fully convective, different from that of the partly-convective Sun-like stars. Magnetic field gene…
Further study of starspot activity and measurement of differential rotation for SZ Piscium
Yue Xiang, Shenghong Gu, A. Collier Cameron +2
We present a series of 9 Doppler images of the magnetically active K component of the RS CVn-type binary SZ Psc, based on the high-resolution spectroscopic data collected from 2014…
