The study of eclipsing binary star systems is one of the most mature and rewarding areas of stellar physics, offering the unique opportunity to determine the masses and radii of distant stars directly from observational data. This area of research is currently experiencing a renaissance, due to the remarkable quality and quantity of data coming from space-based searches for extrasolar planets. Major contributors to this new era are the recent Kepler and CoRoT telescopes, the ongoing K2 and BRITE missions, and the forthcoming space satellites TESS and PLATO. The successful candidate will study eclipsing binary star systems which have been observed with the Kepler, K2, CoRoT and BRITE telescope missions. Follow-up spectroscopic observations have already been obtained for some of these objects and opportunities exist to visit large telescopes to obtain spectroscopic observations of others. The fundamental aim of this project is to verify and improve the predictions of theoretical models of stars, which form the foundation of most areas of observational and theoretical astrophysics.

食双星星星系统的研究是恒星物理学中最成熟和最有价值的领域之一，它提供了直接从观测数据确定遥远恒星的质量和半径的独特机会。这一研究领域目前正在经历复兴，这是由于来自太阳系外行星天基搜索的数据的质量和数量都非常出色。这个新时代的主要贡献者是最近的开普勒和CoRoT望远镜，正在进行的K2和BRITE任务，以及即将发射的TESS和PLATO太空卫星。成功的候选人将研究用开普勒、K2、CoRoT和BRITE望远镜任务观测到的食双星星星系统。已经对其中一些天体进行了后续分光观测，还有机会利用大型望远镜对其他天体进行分光观测。该项目的基本目标是验证和改进恒星理论模型的预测，这些模型构成了观测和理论天体物理学大多数领域的基础。
