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…
Spatial metallicity variations of mono-temperature stellar populations revealed by early-type stars in LAMOST
Chun Wang, Haibo Yuan, Maosheng Xiang +3
We investigate the radial metallicity gradients and azimuthal metallicity distributions on the Galactocentric -- plane using mono-temperature stellar populations selected fro…
Ba-enhanced dwarf and subgiant stars in the LAMOST Galactic surveys
Meng Zhang, Maosheng Xiang, Hua-Wei Zhang +3
Ba-enhanced stars are interesting probes of stellar astrophysics and Galactic formation history. In this work, we investigate the chemistry and kinematics for a large sample of Ba-…
An Ap star catalog based on LAMOST DR9
Fangfei Shi, Huawei Zhang, Jianning Fu +2
We present a sample of 2700 Ap stars in LAMOST DR9. The candidates are first selected to be in a temperature range typical of Ap stars by using the - color index from Gaia…
The Poor Old Heart of the Milky Way
Hans-Walter Rix, Vedant Chandra, René Andrae +9
Massive disk galaxies like our Milky Way should host an ancient, metal-poor, and centrally concentrated stellar population. This population reflects the star formation and enrichme…
Analysis of high-resolution FEROS spectroscopy for a sample of variable B-type stars assembled from TESS photometry
Sarah Gebruers, Andrew Tkachenko, Dominic M. Bowman +8
Spectroscopic data are necessary to break degeneracies in asteroseismic modelling of the interior structure in high- and intermediate-mass stars. We derive precise photospheric ste…
