All-Sky Exoplanetology using NASA's Kepler, K2 and TESS Missions

在过去的十年里，美国宇航局的开普勒、K2和TESS太空任务通过发现数千颗围绕其他恒星运行的行星，彻底改变了天文学。该项目将首次结合这些任务的数据，对系外行星及其主恒星进行均匀的全天表征，并使用地面望远镜进行后续观测，以精确确定系外行星系统的质量和结构。预期的结果包括首次洞察银河系中不同恒星群中小型系外行星的半径分布如何变化，以及在巨大系外行星的形成、组成和演化方面的突破性发现。

The NASA space missions Kepler, K2 and TESS have revolutionized astronomy over the past decade through the discovery of thousands of planets orbiting other stars. This project will for the first time combine the data from these missions to perform a homogeneous all-sky characterization of exoplanets and their host stars, and perform follow-up observations using ground-based telescopes to precisely determine masses and architectures of exoplanet systems. The expected outcomes include the first insights into how the radius distribution of small exoplanets varies among different populations of stars in our Galaxy, and breakthrough discoveries into the formation, composition, and evolution of giant exoplanets.
