Potential Impact of the Sagittarius Dwarf Galaxy on the Formation of Young O-rich Stars
Tiancheng Sun, Shaolan Bi, Xunzhou Chen +11
The Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notab…
Does the scaling relation depend on metallicity? Insights from 3D convection simulations
Yixiao Zhou, Jørgen Christensen-Dalsgaard, Martin Asplund +4
Solar-like oscillations have been detected in thousands of stars thanks to modern space missions. These oscillations have been used to measure stellar masses and ages, which have b…
Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis
Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31
The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…
Investigating 16 Open Clusters in the Kepler/K2-Gaia DR3 field. I. Membership, Binary, and Rotation
Liu Long, Shanlao Bi, Jinhua Zhang +9
Using data from the Gaia Data Release 3 (Gaia DR3) and Kepler/K2, we present a catalog of 16 open clusters with ages ranging from 4 to 4000 Myr, which provides detailed information…
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…
TESS Asteroseismic Analysis of HD 76920: The Giant Star Hosting An Extremely Eccentric Exoplanet
Chen Jiang, Tao Wu, Adina D. Feinstein +30
The Transiting Exoplanet Survey Satellite (TESS) mission searches for new exoplanets. The observing strategy of TESS results in high-precision photometry of millions of stars acros…
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…
