A Study of Stochastic Low-Frequency Variability for Galactic O-type Stars
Dong-Xiang Shen, Chun-Hua Zhu, Guo-Liang Lv +2
In order to explore how the ubiquitous stochastic low-frequency (SLF) variability of O-type stars is related to various stellar characteristics, we compiled a sample of 150 O-type…
Variability of magnetic hot stars from the TESS observations
Dong-Xiang Shen, Gang Li, Iskandar Abdusamatjan +7
Magnetic hot stars refer to the stars, which effective temperatures approximately in the range from 7,000 to 50,000 K, and with large-scale globally organized magnetic fields. Thes…
EOS-dependent millihertz quasi-periodic oscillation in low-mass X-ray binary
Helei Liu, Yong Gao, Zhaosheng Li +4
We studied the frequency and critical mass accretion rate of millihertz quasi-periodic oscillations (mHz QPOs) using a one-zone X-ray burst model. The surface gravity is specified…
A catalogue and statistical analysis for magnetic stars
Abdurepqet Rustem, Guoliang Lv, Jinzhong Liu +5
Magnetic fields are significant in the structure and evolution of stars. We present a comprehensive catalogue of 1784 known magnetic stars, detailing their identifications, HD numb…
