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.

食双星系统的研究是恒星物理学最成熟和最有价值的领域之一，为直接从观测数据确定遥远恒星的质量和半径提供了独特的机会。由于基于太空的太阳系外行星搜索所提供的数据质量和数量都非常出色，这一研究领域目前正在经历复兴。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 任务以及即将推出的太空卫星 TESS 和 PLATO。成功的候选人将研究开普勒、K2、CoRoT 和 BRITE 望远镜任务观测到的食双星系统。已经对其中一些天体进行了后续光谱观测，并且有机会访问大型望远镜以获得其他天体的光谱观测。该项目的根本目的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。
