[62.09] Combining Astrometric and Radial Velocity Techniques for Detecting Outer Planets

J. A. Eisner, S. R. Kulkarni (Astronomy Department, California Institute of Technology)

With the advent of powerful new optical interferometers like Keck Interferometer and SIM, sensitive searches for the astrometric signatures of extra-solar planets will become possible. These searches will supplement sensitive radial velocity surveys that are currently underway. We are investigating the benefits of combining astrometric and radial velocity observations for detecting extra-solar planets. We find that combined astrometric and radial velocity observations yield significant increases in sensitivity, especially for outer planets, than either astrometric or radial velocity observations alone.
