论文摘要
我们提出了HD-TESS，该目录是来自Henry Draper（HD）目录中的1,709个Bright（$ V \ sim3-10 $）红色巨头，并基于NASA的STEROSESIC测量值，该目录基于NASA的STEROSESIC测量值，该测量值基于NASA的过境外部外球运动卫星（TESS）。使用在单个苔丝观察周期中跨越至少六个月的光曲线，我们为目录中的每个恒星提供了全局式呼吸参数（$ν_ {\ mathrm {max}} $和$Δν$）的测量。我们采用大气恒星参数的文献价值来估计目录中巨人的质量和半径，并观察到与开普勒红色巨人相比，HD-Tess巨人平均具有更大的质量。此外，我们介绍了在天文二进制系统中的99个红色巨人中发现振荡的，包括具有分子或白矮人伴侣的振荡。最后，我们对使用长基线干涉法对18个红色巨人进行测量的小星形缩放关系的半径基准了半径，发现缩放关系的校正因子改善了小星言震（Atterose普se）与大约3％之间的一致性。
We present HD-TESS, a catalog of 1,709 bright ($V\sim3-10$) red giants from the Henry Draper (HD) Catalog with asteroseismic measurements based on photometry from NASA's Transiting Exoplanet Survey Satellite (TESS). Using light curves spanning at least six months across a single TESS observing cycle, we provide measurements of global asteroseismic parameters ($ν_{\mathrm{max}}$ and $Δν$) and evolutionary state for each star in the catalog. We adopt literature values of atmospheric stellar parameters to estimate the masses and radii of the giants in our catalog using asteroseismic scaling relations, and observe that HD-TESS giants on average have larger masses compared to Kepler red giants. Additionally, we present the discovery of oscillations in 99 red giants in astrometric binary systems, including those with subdwarf or white dwarf companions. Finally, we benchmark radii from asteroseismic scaling relations against those measured using long-baseline interferometry for 18 red giants and find that correction factors to the scaling relations improve the agreement between asteroseismic and interferometric radii to approximately 3%.
