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…
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…
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…
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…
Stellar cycle and evolution of polar spots in an M+WD binary
Xinlin Zhao, Song Wang, Xue Li +4
Stellar activity cycles reveal continuous relaxation and induction of magnetic fields. The activity cycle is typically traced through the observation of cyclic variations in total…
