THE SEARCH FOR OTHER WORLDS: Fourteenth Astrophysics Conference. AIP Conference Proceedings, Volume 713, pp. 31-34 (2004). (AIPC Homepage)
We present an overview of our ongoing systematic search for wide (sub)stellar companions around the stars known to host rad-vel planets. By using a relatively large field of view and going very deep, our survey can find all directly detectable stellar and massive brown dwarf companions (m>40 MJup) within a 1000 AU orbit.
