论文摘要
本文总结了有关太空卫星数据的Erasmus+ Gate 2020 Summer School的Asterosology项目的项目。目的是对KIC 5006817进行全球的Asterosic分析，并使用高质量的，最先进的空间任务数据来量化其恒星性能。我们采用了光圈光度法来分析开普勒太空望远镜和过境系外行星调查卫星（TESS）的数据。使用LightKurve Python软件包，我们得出了Asteroseiscic参数，并使用缩放关系计算了恒星参数。我们对KIC 5006817的分析证实了其分类为心跳二元。丰富的振荡频谱促进了145.50 $ \ pm $ 0.50 $μ$ Hz和大频率分离（$δν$）的估计量超过（$ν_ {\ rm max} $），为11.63 $ \ $ \ pm $ 0.10 $ $ $ $ $ $ $ $ Hz。 Our results showed that the primary component is a low-luminosity, red-giant branch star with a mass, radius, surface gravity, and luminosity of 1.53$\pm$0.07 M$_\odot$, 5.91$\pm$0.12 R$_\odot$, 3.08$\pm$0.01 dex, and 19.66$\pm$0.73 L$_\odot$, 分别。系统的轨道周期为94.83 $ \ pm $ 0.05 d。
This paper summarizes the project work on asteroseismology at the ERASMUS+ GATE 2020 Summer school on space satellite data. The aim was to do a global asteroseismic analysis of KIC 5006817 and quantify its stellar properties using the high-quality, state of the art space missions data. We employed the aperture photometry to analyze the data from the Kepler space telescope and the Transiting Exoplanet Survey Satellite (TESS). Using the lightkurve Python package, we have derived the asteroseismic parameters and calculated the stellar parameters using the scaling relations. Our analysis of KIC 5006817 confirmed its classification as a heartbeat binary. The rich oscillation spectrum facilitate estimating power excess ($ν_{\rm max}$) at 145.50$\pm$0.50 $μ$Hz and large frequency separation ($Δν$) to be 11.63$\pm$0.10 $μ$Hz. Our results showed that the primary component is a low-luminosity, red-giant branch star with a mass, radius, surface gravity, and luminosity of 1.53$\pm$0.07 M$_\odot$, 5.91$\pm$0.12 R$_\odot$, 3.08$\pm$0.01 dex, and 19.66$\pm$0.73 L$_\odot$, respectively. The orbital period of the system is 94.83$\pm$0.05 d.
