Photometric Stellar Parameters for 195,478 Kepler Input Catalog (KIC) Stars
Bowen Zhang, Yang Huang, Timothy C. Beers +9
The stellar atmospheric parameters and physical properties of stars in the Kepler Input Catalog (KIC) are of great significance for the study of exoplanets, stellar activity, and a…
Revisiting the activity-rotation relation for evolved stars
Henggeng Han, Song Wang, Xue Li +2
The magnetic dynamo mechanism of giant stars remains an open question, which can be explored by investigating their activity-rotation relations with multiple proxies. By using the…
Ultraviolet Photometry and Habitable Zones of Over 2700 Planet-Hosting Stars
Xue Li, Song Wang, Henggeng Han +1
The ongoing discovery of exoplanets has sparked significant interest in finding suitable worlds that could potentially support life. Stellar ultraviolet (UV; 100-3000 Å) radiation…
Double-edged sword: the influence of tidal interaction on stellar activity in binaries
Yuedan Ding, Shidi Zhang, Henggeng Han +4
Using the LAMOST DR7 low-resolution spectra, we carried out a systematic study of stellar chromospheric activity in both single and binary stars. We constructed a binary sample and…
Predicting photospheric UV emission from stellar evolutionary models
Song Wang, Xue Li, Henggeng Han +1
Stellar ultraviolet (UV) emission serves as a crucial indicator for estimating magnetic activity and evaluating the habitability of exoplanets orbiting stars. In this paper, we pre…
Chromospheric modeling of the active M3V star G 80-21 with RH1.5D
Shuai Liu, Huigang Wei, Jianrong Shi +4
This study investigates the active regions of the M3.0V star G 80-21 using the observed data from the CARMENES project with synthetic spectra generated by the RH1.5D radiative tran…
A potential mass-gap black hole in a wide binary with a circular orbit
Wang Song, Zhao Xinlin, Feng Fabo +28
Mass distribution of black holes identified through X-ray emission suggests a paucity of black holes in the mass range of 3 to 5 solar masses. Modified theories have been devised t…
Direct Method to Compute Doppler Beaming Factors in Binary Stars
Chuanjie Zheng, Yang Huang, Jifeng Liu +4
The Doppler beaming effect, induced by the reflex motion of stars, introduces flux modulations and serves as an efficient method to photometrically determine mass functions for a l…
Stellar X-ray activity and habitability revealed by ROSAT sky survey
Henggeng Han, Song Wang, Chuanjie Zheng +3
Using the homogeneous X-ray catalog from ROSAT observations, we conducted a comprehensive investigation into stellar X-ray activity-rotation relations for both single and binary st…
Ultraviolet and Chromospheric activity and Habitability of M stars
Xue Li, Song Wang, Henggeng Han +4
M-type stars are crucial for stellar activity studies since they cover two types of magnetic dynamos and particularly intriguing for habitability studies due to their abundance and…
