Stellar mass plays a key role in studying planet formation, and asteroseismology can provide us with precise model-independent stellar mass. Thanks to TESS precise photometry, we can study the asteroseismology of stars in the whole sky. Inspired by several studies, e.g., Malla et al. (2020), Hon et al. (2022), etc., we investigate the samples within the framework of the East Asian Planet Search Network (EAPS-Net), a planet search program mainly targeting planets around GK giant stars. We first cross the EAPS-Net target list with the TESS catalog. We then screen out stars with clear solar-like oscillations and measure their characteristic oscillation frequency nu_max, and the large frequency parameter Dnu from TESS light curve. We hereafter determine their evolutionary state (RGB/CHeB) using the method in Hon et al. (2018). Finally, we determine the stellar masses of the stars in the EAPS-Net target list. Furthermore, we release one new planet system from the 20-year EAPS-Net RVs.
Huanyu received his B.S. in Astronomy from Beijing Normal University in 2016. Now he is a Ph.D. (2023 expected) candidate at the Tokyo Institute of Technology, supervised by professor Bunei Sato. His current research focuses on (1) the Detection of planet systems around evolved stars, (2) the giant Planet occurrence and giant-planet-metallicity correlation, (3) a Better understanding of radial velocity jitter of evolved stars, (4) planet detection and characterization around mid-to-late M dwarfs.
