Age of FGK Dwarfs Observed with LAMOST and GALAH: Considering the Oxygen Enhancement
Tiancheng Sun, Zhishuai Ge, Xunzhou Chen +11
Varying oxygen abundance could impact the modeling-inferred ages. This work aims to estimate the ages of dwarfs considering observed oxygen abundance. To characterize 67,503 LAMOST…
Asteroseismic Modeling of 1,153 Kepler Red Giant Branch Stars: Improved Stellar Parameters with Gravity-Mode Period Spacings and Luminosity Constraints
Yingxiang Wang, Tanda Li, Shaolan Bi +2
This paper reports estimated stellar parameters of 1,153 Kepler red giant branch stars determined with asteroseismic modeling. We use radial-mode oscillation frequencies, gravity-m…
Revised extinctions and radii for 1.5 million stars observed by APOGEE, GALAH, and RAVE
Jie Yu, Shourya Khanna, Nathalie Themessl +4
Asteroseismology has become widely accepted as a benchmark for accurate and precise fundamental stellar properties. It can therefore be used to validate and calibrate stellar param…
Discovery of post-mass-transfer helium-burning red giants using asteroseismology
Yaguang Li, Timothy R. Bedding, Simon J. Murphy +14
A star expands to become a red giant when it has fused all the hydrogen in its core into helium. If the star is in a binary system, its envelope can overflow onto its companion or…
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…
LAMOST Time-Domain Survey: First Results of four 2 plates
Song Wang, Haotong Zhang, Zhongrui Bai +23
From Oct. 2019 to Apr. 2020, LAMOST performs a time-domain spectroscopic survey of four 2 plates with both low- and med-resolution observations. The low-resolution spectroscopic…
