目标。我们研究了一种超越凌日法探测系外行星伴星的新方法。我们讨论了“双行星”存在的可能性。方法。我们开发了一种基于将行星伴星成像为未解析系统（但从其母恒星中解析）的方法。它利用了行星伴星的“相互现象”，即相互凌日和相互阴影。结果。我们发现伴星可以被探测到，它们的半径可以测量到月球大小。
Aims. We investigate a new approach to the detection of companions to extrasolar planets beyond the transit method. We discuss the possibility of the existence of "binary planets". Methods. We develop a method based on the imaging of a planet-companion as an unresolved system (but resolved from its parent star). It makes use of planet-companion "mutual phenomena", namely mutual transits and mutual shadows. Results. We show that companions can be detected and their radius measured down to lunar sizes.
