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…
