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…
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…
Distribution of fast radio burst dispersion measures in CHIME/FRB Catalog 1: implications on the origin of FRBs
Jianwei Zhang, Chengmin Zhang, Di Li +7
Recently, CHIME/FRB project published its first fast radio burst (FRB) catalog (hereafter, Catalog 1), which totally contains 536 unique bursts. With the help of the latest set of…
