The SAAO program committee has granted us one week (19-25 June 2013) of observation time for our project "Exoplanets in eclipsing ost-common-envelope binary systems" at the 1.9m telescope of the South African Astronomical Observatory (SAAO) in Sutherland.The purpose of the program is the detection of planets around evolved binary stars that have already gone through the phase of a common hull and occult each other once per orbit. To do so we take time series of the binary systems and look for variations in the periods, which indicate the existance of another object in the systems. The planned observations are part of an existing project, in which we have observed some of the objects with our own Monet telescopes as well with the 10m class telescope SALT in Sutherland. In November 2012 we already had the opportunity to do obervations with the 1.9m telescope in Sutherland, giving us experience with the instrument. The obtained data is of good quality, but not published yet.Further observations with the 1.9m telescope at the SAAO will allow us to extend our existing data quickly.

SAAO计划委员会授予我们为期一周（2013年6月19日至25日）的观测时间，用于我们的项目“食共包层双星系统中的系外行星”，该项目使用位于萨瑟兰的南非天文台（SAAO）的1.9m望远镜。该计划的目的是探测演化双星周围的行星，这些行星已经经历了共同外壳阶段并相互隐匿。 每个轨道一次。为此，我们采用双星系统的时间序列并寻找周期的变化，这表明系统中存在另一个物体。计划中的观测是现有项目的一部分，在该项目中，我们使用自己的莫奈望远镜以及位于萨瑟兰的 10m 级望远镜 SALT 观测了一些天体。 2012年11月，我们已经有机会使用萨瑟兰的1.9m望远镜进行观测，让我们体验到了该仪器的使用。获得的数据质量很好，但尚未发表。利用SAAO的1.9m望远镜进行进一步观测将使我们能够快速扩展现有数据。
