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…

Detection of dark companions via the combination of eclipse timing variation, Hipparcos and/or Gaia astrometry: the cases of V Puppis and CY Ari

Guang-Yao Xiao, Fabo Feng, Song Wang +3

The third body is expected to shape the formation and evolution of close binary systems. In this work, we develop a method to detect and characterize the tertiary companion around…

Search for Radio Pulsations from Neutron Star Candidates in Detached Binaries

Shi-Jie Gao, Xiang-Dong Li, Song Wang +7

Recent optical astrometric and spectroscopic surveys have identified numerous neutron star (NS) candidates in non-accreting detached binary systems, but their compact-object nature…

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…

Revisiting the Li abundances of Stars with and without Detected Planets from the High Resolution Spectroscopy

Jinxiao Qin, Hong-Liang Yan, Wenyuan Cui +12

Whether the presence of planets affects the lithium (Li) abundance of their host stars is still an open question. To investigate the difference of the Li abundance between planet-h…
