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…
