Formation of black holes from He stars
Gang Long, Bo Wang, Philipp Podsiadlowski +5
Massive He stars are potential candidates of type Ib/c supernova (SN) progenitors. Understanding their final fates remains a key issue in astrophysics. In this work, we investigate…
Measuring the magnetic fields in the chromospheres of low-mass stars
Tianqi Cang, Pascal Petit, Jean-François Donati +11
Magnetic fields in the upper atmospheres of solar-like stars are believed to provide an enormous amount of energy to power the hot coronae and drive large-scale eruptions that coul…
Starspots as the origin of ultrafast drifting radio bursts from an active M dwarf
Jiale Zhang, Hui Tian, Stefano Bellotti +16
Detecting coherent radio bursts from nearby M dwarfs provides opportunities for exploring their magnetic activity and interaction with orbiting exoplanets. However, it remains unce…
The formation of the stripped envelope type II b Supernova progenitors: Rotation, Metallicity and Overshooting
Gang Long, Hanfeng Song, Georges Meynet +6
Type IIb supernovae are believed to originate from core-collapse progenitors having kept only a very thin hydrogen envelope. We aim to explore how some physical factors, such as ro…
Characteristic time of stellar flares on Sun-like stars
Y. Yan, H. He, C. Li +4
Using the short-cadence data (1-min interval) of the Kepler space telescope, we conducted a statistical analysis for the characteristic time of stellar flares on Sun-like stars (SL…
Stellar activity with LAMOST. III. Temporal variability pattern in Pleiades, Praesepe, and Hyades
Xiang-Song Fang, Christian Moni Bidin, Gang Zhao +2
We present the results from a systematic study of temporal variation of stellar activity in young late-type stars. We used multi-epoch LAMOST low-resolution spectra of over 300 mem…
