Planets orbiting both stars of a binary system -circumbinary planets- are challenging what we think we knowabout how exoplanets are assembled, and how their orbits subsequently evolve. Because they orbit oneanother, binary stars disturb the process of core accretion that creates planets. But, instead of changing thenumber of planets created, the two stars instead affects circumbinary planets' masses and orbital separations,thus shining an unexpected light onto which planet formation processes are truly important. With itsambitious programme, CandY will consolidate circumbinary planets as an unavoidable corner ofexoplanetary science, crucial for the study of planet formation, and the study and interpretation of exoatmospheres.To better our understanding of planet formation, the CandY project will perform the first systematic study ofcircumbinary planets. CandY will develop a suite of new analytical methods, and conduct three ambitiousobserving campaigns that will lead to the detection of dozens of new circumbinary planets, including someall way down to rocky masses. In parallel, the CandY team will study the atmospheric composition ofcircumbinary planets for the very first time in order to reveal yet more clues about these exotic worlds.During the CandY project, we will record every similarity, and any difference between the population ofcircumbinary planets and the population of exoplanets orbiting single stars. This systematic exercise willcreate a leap in our understanding about how planets are produced and which processes dominate planetassembly and their subsequent orbital migration.In addition, circumbinary planets have unique orbital properties amongst exoplanets. Their orbital dynamicsboost their probability to experience transits easing exo-atmospheric investigations. Moreover, circumbinaryexoplanets are the only transiting planets for which seasonal atmospheric variations can be studied.

绕着二进制系统的两个星星绕的行星 - 圆环行星 - 都在挑战我们认为我们知道外部球星的组装方式，以及它们的轨道随后如何发展。因为它们绕了Oneanother Oneanother，所以二进制恒星干扰了创建行星的核心积聚过程。但是，这两个恒星没有改变创造的行星，而是影响了环形行星的质量和轨道隔离，从而使行星形成过程真正重要的意外灯光照亮了意想不到的光线。借助其雄心勃勃的计划，Candy将巩固环形行星是跨界科学的不可避免的角落，对于行星形成的研究至关重要，以及对exotmospheres的研究和解释。为了更好地理解我们对行星形成的理解，糖果项目将执行首个系统的系统研究。 Candy将开发一系列新的分析方法，并进行三场雄心勃勃的运动，这将导致发现数​​十个新的环球行星，包括Someall Way，降到岩石群众。同时，糖果团队将首次研究圆环行星的大气组成，以揭示有关这些异国情调的世界的更多线索。在糖果项目中，我们将记录所有相似之处，以及圈子行星的种群和exoplanets旋转单星的人群之间的任何差异。这种系统的练习将在我们对行星的生产方式以及哪些过程主导的行星及其随后的轨道迁移中的理解中产生飞跃。此外，环形行星在系外行星之间具有独特的轨道特性。他们的轨道动力学启动他们经历过境的可能性宽松的大气调查的可能性。此外，环形外环星是可以研究季节性大气变化的唯一过境行星。
