Characterising abundance-age relations of GALAH stars using oxygen-enhanced stellar models
Tiancheng Sun, Xunzhou Chen, Shaolan Bi +3
Main Sequence Turn-off stars (MSTO) and subgiant stars are good tracers of galactic populations. We present a study of 41,034 MSTO and subgiant stars from the GALAH survey. Using a…
The role of radial migration on tracing lithium evolution in the Galactic disk
Haopeng Zhang, Yuqin Chen, Gang Zhao +3
With the calculated guiding center radius and birth radius , we investigate the role of radial migration on the description of lithium evolution in the Gal…
Timing the formation of the Galactic thin disc with asteroseismic stellar ages
Wu Yaqian, Xiang Maosheng, Zhao Gang +3
The formation of the extended thin disc is the most spectacular event of our Galaxy in the past \,Gyr. To unveil this process, obtaining precise and accurate stellar ages fo…
Overview of the LAMOST survey in the first decade
Hongliang Yan, Haining Li, Song Wang +24
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), also known as the Guoshoujing Telescope, is a major national scientific facility for astronomical research l…
Age-metallicity dependent stellar kinematics of the Milky Way disc from LAMOST and Gaia
Yaqian Wu, Maosheng Xiang, Yuqin Chen +5
We investigate the stellar kinematics of the Galactic disc in 7 13\,kpc using a sample of 118\,945 red giant branch (RGB) stars from LAMOST and Gaia. We characterize th…
A note on periodicity of long-term variations of optical continuum in active galactic nuclei
Kai-Xing Lu, Yan-Rong Li, Shao-Lan Bi +1
Graham et al. found a sample of active galactic nuclei (AGNs) and quasars from the Catalina Real-time Transient Survey (CRTS) that have long-term periodic variations in optical con…
