Main-sequence Turnoff Stars as Probes of the Ancient Galactic Relic: Chemo-dynamical Analysis of a Pilot Sample
Renjing Xie, Haining Li, Ruizhi Zhang +5
The main-sequence turnoff (MSTO) stars well preserve the chemical properties where they were born, making them ideal tracers for studying the stellar population. We perform a detai…
Discovery of an Extremely r-process-enhanced Thin-disk Star with [Eu/H] = +0.78
Xiao-Jin Xie, Jianrong Shi, Hong-Liang Yan +9
Highly r-process-enhanced stars are rare and usually metal-poor ([Fe/H] < - 1.0), and mainly populate the Milky Way halo and dwarf galaxies. This study presents the discovery of a…
Lithium Abundances from the LAMOST Med-Resolution Survey Data Release 9
Ming-Yi Ding, Jian-Rong Shi, Hong-liang Yan +9
Lithium is a fragile but crucial chemical element in the universe, exhibits interesting and complex behaviors. Thanks to the massive spectroscopic data from the Large Sky Area Mult…
Stellar Atmospheric Parameters of M-type Stars from LAMOST DR8
Ming-Yi Ding, Jian-Rong Shi, Yue Wu +9
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low Resolution Spectroscopic Survey (LRS) provides massive spectroscopic data of M-type stars, and the derive…
MagAO observations of the binary microlens OGLE-2014-BLG-1050 prefer the higher-mass solution
Xiaojia Xie, Subo Dong, Wei Zhu +9
We report adaptive-optics (AO) follow-up imaging of OGLE-2014-BLG-1050, which is the second binary microlensing event with space-based parallax measurements. The degeneracy in micr…
A Wide Orbit Exoplanet OGLE-2012-BLG-0838Lb
Poleski R., Suzuki D., Udalski A. +48
We present the discovery of a planet on a very wide orbit in the microlensing event OGLE-2012-BLG-0838. The signal of the planet is well separated from the main peak of the event a…
