Scientific paper

We will present the first results from our on-going radial velocity survey for circumbinary planets. The survey is possible thanks to our novel radial velocity technique employing an iodine absorption cell which for the first time allows us to reach single m/s RV precision for double-lined binary stars. Based on the spectra collected with the Keck I/Hires, TNG/Sarg, and Shane/CAT/Hamspec telescopes/spectrographs over the years 2003-2008 we obtained planet detection limits for a sample of double-lined binary stars. For this initial sample of targets, we can rule out planets on dynamically stable orbits with masses as small as 0.3 to 3MJup for the orbital periods of up to 5.3 years.
