A chemo-dynamical search for planet-candidate hosts of possible extragalactic origin

Sun Tiancheng, Chen Xunzhou, Xiang Maosheng +2

To date, all known exoplanetary systems have been identified around stars currently residing in the Milky Way, whereas planets formed in external galaxies remain largely unexplored…

Unraveling Year-Long Radial Velocity Variations in Red Clump Region -- I: Comprehensive analysis of a K0 Giant star, 2 Draconis

Udomlerd Srisuchinwong, Jianzhao Zhou, Huan-Yu Teng +18

Slow-rotating evolved stars frequently exhibit radial velocity (RV) variations on annual timescales, complicated by instrumental systematics and aliasing in the one-year regime. He…

Relations of rotation and chromospheric activity to stellar age for FGK dwarfs from Kepler and LAMOST

Lifei Ye, Shaolan Bi, Jinghua Zhang +9

The empirical relations between rotation period, chromospheric activity, and age can be used to estimate stellar age. To calibrate these relations, we present a catalog, including…

Detection of Solar-like Oscillations in Sub-giant and Red Giant Stars Using 2-minute Cadence TESS Data

Jianzhao Zhou, Shaolan Bi, Jie Yu +7

Based on all 2-minute cadence light curves from Sector 1 to 60, we provide a catalog of 8,651 solar-like oscillators, including frequency at maximum power (, wi…

Two long-period giant planets around two giant stars: HD 112570 and HD 154391

Guang-Yao Xiao, Huan-Yu Teng, Jianzhao Zhou +24

We present the discoveries of two giant planets orbiting the red giant branch (RGB) star HD 112570 and the red clump (RC) star HD 154391, based on the radial velocity (RV) measurem…

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…

Revisit NGC 5466 Tidal Stream with , SDSS/SEGUE and LAMOST

Yong Yang, Jing-Kun Zhao, Miho N. Ishigaki +5

By mining the data from EDR3, SDSS/SEGUE DR16 and LAMOST DR8, 11 member stars of the NGC 5466 tidal stream are detected and 7 of them are newly identified. To reject contami…
