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

• Applicant: Dr. Tim-Oliver Husser
• Subject Area: Astrophysics and Astronomy
• Term: from 2013 to 2015
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 242483342

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.
