  • 摘要:We present HD-TESS, a catalog of 1709 bright (V ∼ 3–10) red giants from the Henry Draper (HD) Catalog withasteroseismic measurements based on photometry from NASA’s Transiting Exoplanet Survey Satellite (TESS).Using light curves spanning at least 6 months across a single TESS observing cycle, we provide measurements ofglobal asteroseismic parameters (nmax and Δν) and the evolutionary state for each star in the catalog. We adoptliterature values of atmospheric stellar parameters to estimate the masses and radii of the giants in our catalog usingasteroseismic scaling relations, and observe that HD-TESS giants on average have larger masses compared toKepler red giants. Additionally, we present the discovery of oscillations in 99 red giants in astrometric binarysystems, including those with subdwarf or white dwarf companions. Finally, we benchmark radii fromasteroseismic scaling relations against those measured using long-baseline interferometry for 18 red giants and findthat correction factors to the scaling relations improve the agreement between asteroseismic and interferometricradii to approximately 3%.
