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

南非天文台计划委员会给了我们一周(2013年6月19日至25日)的观测时间，用于我们在南非萨瑟兰天文台1.9米望远镜上进行的“遮蔽最普通包层双星系中的系外行星”项目。该项目的目的是探测已经经历共同外壳阶段的演化双星周围的行星，并在每个轨道上相互遮蔽一次。为此，我们获取二进制系统的时间序列，并寻找周期中的变化，这表明系统中存在另一个对象。计划中的观测是现有项目的一部分，在该项目中，我们已经用我们自己的莫奈望远镜以及萨瑟兰的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1.9米望远镜进行观测，这给了我们使用该仪器的经验。获得的数据质量很好，但还没有公布。用SAAO的1.9米望远镜进行进一步的观测，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.
