Ages of Main-Sequence Turn-Off Stars from the GALAH Survey
Xunzhou Chen, Zhishuai Ge, Yuqin Chen +6
Main sequence turn-off (MSTO) stars are good tracers of Galactic populations since their ages can be reliably estimated from atmospheric parameters. Based on the GALAH survey, we u…
A Catalog of RV Variable Star Candidates from LAMOST
Zhijia Tian, Xiaowei Liu, Haibo Yuan +14
RV variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ~ 6.5 million stellar spec…
Rotating Solar Models with Low Metal Abundances as Good as Those with High Metal Abundances
Wuming Yang
Standard solar models (SSM) constructed in accord with low metal abundances disagree with the seismically inferred results. We constructed rotating solar models with low metal abun…

\textbf{Scaling formulas were} deduced to describe the relations between the fundamental stellar parameters and the mean \textbf{linewidth and lifetime} of solar-like oscillations…
The Effects of Binary Stars on the Color-Magnitude Diagrams of Young-Age Massive Star Clusters
Wuming Yang
Extended main-sequence turnoffs (eMSTO) have been observed in the color-magnitude diagram (CMD) of intermediate-age and young star clusters. The origin of the eMSTO phenomenon is s…
Binary Star Fractions from the LAMOST DR4
Zhijia Tian, Xiaowei Liu, Haibo Yuan +17
Stellar systems composed of single, double, triple or high-order systems are rightfully regarded as the fundamental building blocks of the Milky Way. Binary stars play an important…
The effects of the overshooting of the convective core on main-sequence turnoffs of young- and intermediate-age star clusters
Wuming Yang, Zhijia Tian
Recent investigations have shown that the extended main-sequence turnoffs (eMSTOs) are a common feature of intermediate-age star clusters in the Magellanic Clouds. The eMSTOs are a…
Asteroseismic analysis of two alpha-enhanced stars KIC 7976303 and KIC 8694723
Z. S. Ge, S. L. Bi, T. D. Li +5
We intent to use stellar models with and without alpha-enhancement, as well as asteroseismic analysis, to study two alpha-enhanced stars, KIC 7976303 and KIC 8694723. For the alpha…
Estimate the radius of the convective core of main-sequence stars from observed oscillation frequencies
Wuming Yang
The determination of the size of the convective core of main-sequence stars is usually dependent on the construction of models of stars. Here we introduce a method to estimate the…
Solar models with new low-metal abundances
Wuming Yang
In the last decade, the photospheric abundances of the Sun had been revised several times by many observers. The standard solar models (SSM) constructed with the new low-metal abun…

Wuming Yang, Zhijia Tian, Shaolan Bi +3
The ratios and of small to large separations of KIC 2837475 primarily exhibit an increase behavior in the observed frequency range. The calculations indicate that…
A Large Convective-Core Overshoot in \textit{Kepler} Target KIC 11081729
Wuming Yang
The frequency ratios and of KIC 11081729 decrease firstly and then increase with the increase in frequency. For different spectroscopic constraints, all models wi…
