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…
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…
Search for double-line spectroscopic binaries in RAVE survey
Mikhail Kovalev
The paper analyzes RAVE survey spectra to identify double-line spectroscopic binaries using a composite spectral model, finding 2,813 composite spectra across 2,605 targets and val…
Research Progress on Solar Small-Scale Dynamo
Wen-Jie Jiang, Lei Ni, Chun-Lan Jin +2
The small-scale solar dynamo theory, as the core mechanism explaining the origin of the persistent, disperse weak magnetic field in the quiet Sun regions, has made significant prog…
Research on the Flat Field Measurement Method of Coronagraph
Yulong Feng, Xuefei Zhang, Hongfei Liang +4
The solar corona has an extremely low density, and its brightness is only about one millionth of that of the photosphere. High-dynamic-range imaging of its faint structure is there…
Shortest period for outer orbit in compact hierarchical triple? Discovery of SB1 around V0885 Per
Mikhail Kovalev
I present a discovery of SB1 in the LAMOST-MRS spectra of eclipsing contact binary V 885 Per. Spectroscopic orbit has period only day, which will make it shortest known ou…
