This project aims to combine the first results from the Gaia mission with Kepler data to improve understanding of stars and planets. The study of the structure and evolution of stars and planets in our galaxy is one of the most rapidly growing fields in astronomy. While the NASA Kepler Mission has discovered thousands of exoplanets and oscillating stars, poor knowledge of their distances has been a limitation in exploiting the data. The project is expected to yield an empirical calibration of asteroseismology, and lead to breakthrough discoveries in understanding masses and interior rotation in intermediate mass stars to accurately estimate the frequency of Earth-like planets in our galaxy.

该项目旨在将盖亚使命的第一批结果与开普勒数据相结合，以提高对恒星和行星的了解。研究银河系中恒星和行星的结构和演化是天文学中发展最快的领域之一。虽然美国宇航局开普勒使命已经发现了数千颗系外行星和振荡星，但对它们的距离知之甚少，限制了对数据的利用。该项目预计将产生一个经验校准的星震学，并导致突破性的发现，了解质量和内部旋转的中等质量的恒星，以准确地估计我们的银河系中的类地行星的频率。
