Rotationally modulated highly circularly polarised radio pulses from the rapidly rotating M dwarf ASKAP J181335-604720
Shouzhi Wang, Biwei Jiang, Qichen Huang +2
We report the detection of strong, highly circularly polarised, and rotationally modulated radio pulses from the early-mid M dwarf ASKAP J181335-604720, based on strictly simultane…
The Extinction Distance of Supernova Remnants in Combination with the CO Line Measurements
Zhe Zhang, Jun Li, Biwei Jiang +2
Accurate distance measurements to supernova remnants (SNRs) are crucial for understanding their physical properties and evolution. We present a novel method that combines CO line o…
An Enhanced Sample of Galactic Red Supergiants Reveals Spiral Structures
Zehao Zhang, Biwei Jiang, Yi Ren
Red supergiants (RSGs), representing a kind of massive young stellar population, have rarely been used to probe the structure of the Milky Way, mainly due to the long-standing scar…
The structural and kinematical properties of NGC 5634, a globular cluster associated with the Sagittarius dwarf galaxy?
Shouzhi Wang, Jundan Nie, Biwei Jiang +3
We investigate the origin of NGC 5634 through a comprehensive analysis of its morphology, kinematics and dynamics. Utilizing data from the DESI Legacy Survey, we refined its fundam…
The Samples and Binary Fractions of Red Supergiant in M31 and M33 by the HST Observations
Min Dai, Shu Wang, Biwei Jiang +1
The binarity of red supergiants (RSGs) influences their evolution and the fate of supernovae. We investigate the binary fraction of RSGs in the Andromeda Galaxy (M31) and Triangulu…
Massive Acquisition of Ultraviolet Color Excess Information from GALEX and UVOT Bands
Dongliang Yang, Mingxu Sun, Biwei Jiang +4
This study employs stellar parameters from spectroscopic surveys and Zhang et al. based on Gaia XP spectra, along with photometric data from GALEX, UVOT, and Gaia, to obtain extens…
