Astronomical observations at the 1.9m telescope of the South African Astronomical Observatory in Sutherland, South Africa

南非天文台（SAAO）计划委员会已经批准我们在萨瑟兰的南非天文台（SAAO）的1.9米望远镜上进行为期一周（2013年6月19日至25日）的观测时间，用于我们的项目“外行星在食常包络双星系统”。该计划的目的是探测进化双星周围的行星，这些行星已经经历了共同外壳的阶段，并且每个轨道都隐蔽一次。为此，我们采用二进制系统的时间序列，并寻找周期的变化，这表明系统中存在另一个对象。计划中的观测是一个现有项目的一部分，在这个项目中，我们用我们自己的莫奈望远镜以及萨瑟兰的10米级望远镜SALT观察了一些物体。2012年11月，我们已经有机会在萨瑟兰用1.9米的望远镜进行观测，让我们有了使用仪器的经验。获得的数据质量很好，但尚未发表。SAAO上1.9米望远镜的进一步观测将使我们能够迅速扩展现有数据。

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.
