Abstract

We present preliminary results of the first and on-going radial velocity survey for circumbinary planets. With a novel radial velocity technique employing an iodine absorption cell, we achieve an unprecedented radial velocity (RV) precision of up to 2 m s^(–1) for double-lined binary stars. The high-resolution spectra collected with the Keck I/Hires, TNG/Sarg, and Shane/CAT/Hamspec telescopes/spectrographs over the years 2003-2008 allow us to derive RVs and compute planet detection limits for 10 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 3 M_(Jup) for the orbital periods of up to ~5.3 years. Even though the presented sample of stars is too small to make any strong conclusions, it is clear that the search for circumbinary planets is now technique-wise possible and eventually will provide new constraints for the planet formation theories

We thank Lucasfilm Ltd for inspiring the TATOOINE planet search (and careers of many of us), and Lucasfilm’s Senior Director of Business Affairs David Anderman for an excellent tour of the Lucasfilm complex upon hearing about our program. The tour of Lucasfilm was a highlight of the undergraduate research experiences of Agnieszka Czeszumska, Sam Halverson, Tony Mercer, and Jackie Schwehr. We thank the California and Carnegie Exoplanet Search team, and Geoff Marcy in particular, for allowing us to access their precision velocimetry tools at Lick Observatory.
