Abstract

We revise parameters of four transiting hot Jupiter planets discovered by ground-based surveys. We use follow-up observations carried by TESS mission together with PyTransit software. Space telescopes like TESS provide better coverage and photometry precision than ground-based telescopes. PyTransit is fast and user-friendly exoplanet transit light curve modelling package, implementing optimised versions of the Gimenéz and the Mandel & Agol transit models. After applying PyTransit to TESS data, our results show an improvement in the exoplanets parameters estimation.

基于TESS数据改进系外行星光曲线参数

我们修正了四颗由地面观测发现的凌日热木星行星的参数。我们使用TESS卫星携带的后续观测数据以及PyTransit软件。与地面望远镜相比，像TESS这样的太空望远镜可以提供更好的覆盖范围和测光精度。PyTransit是一款快速且用户友好的系外行星凌日光曲线建模软件包，实现了gimenz和Mandel & Agol凌日模型的优化版本。将PyTransit应用于TESS数据后，我们的结果表明系外行星参数估计有了改进。
