Evolution of Stellar Activity and Habitable Zone (EATEN): III. X-ray Activity of Dwarfs in Open Clusters and Field Stars
Xue Li, Song Wang, Henggeng Han +3
Stellar X-ray emission serves as a direct diagnostic of coronal activity, which is fundamentally linked to coronal heating processes. It also strongly influences the atmospheres an…
Flare waiting time as a novel proxy of stellar magnetic activity
Henggeng Han, Song Wang, Chuanjie Zheng +3
Stellar flares have long served as stellar magnetic activity tracers. The flare waiting time, defined as the interval between two consecutive flares, provides a valuable diagnostic…
Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
G6096 (Gaia DR3 609651611028044544) was recently reported as a wide ( days) and eccentric () binary possibly hosting a massive white dwarf or neutron star. In…
Evolution of Stellar Activity and Habitable Zone II: Ca H&K Emissions of Late-type Dwarfs
Henggeng Han, Song Wang, Xue Li +3
Stellar chromospheric activity serves as a valuable proxy for estimating stellar ages, though its applicable range and accurate functional form are still debated. In this study, ut…
Varying core-envelope coupling efficiency identified from stellar rotation--activity relation
Henggeng Han, Song Wang, Huiqin Yang +5
Core-envelope coupling provides a reasonable explanation of the spin-down stalling of stars in open clusters, which was not predicted by classical gyrochronology. However, it remai…
Evolution of Stellar Activity and Habitable zone: I. Ultraviolet Emission of Dwarfs in Open Clusters and Field Stars
Xue Li, Song Wang, Jun Ma +3
Near-ultraviolet (NUV) radiation from dwarf stars plays a critical role in shaping the habitability of planetary systems, yet its long-term evolution across different spectral type…
Four ages of rotating stars in the rotation--activity relationship and gyrochronology
Huiqin Yang, Jifeng Liu, Roberto Soria +4
Gyrochronology and the rotation--activity relationship are standard techniques used to determine the evolution phase.The mismatch in the definition of the evolutionary phases has s…
Impact of Spectral Resolution on S-index and Its Application to Spectroscopic Surveys
Henggeng Han, Song Wang, Xue Li +2
Utilizing the PHOENIX synthetic spectra, we investigated the impact of spectral resolution on the calculation of -indices. We found that for spectra with a resolution lower than…
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…
