" The brown dwarf desert between 5 and 50 AU probed by combined direct imaging and radial velocity "

Janis Hagelberg

(IfA/University of Geneva)

I will present the results of the completed direct imaging campaign for stars with radial velocity drifts in the HARPS and CORALIE planet-search surveys. Using the radial velocity data which spans over more than a decade, we selected promising targets for direct imaging of sub-stellar companions to solar-type stars. The direct imaging observations were carried out on VLT/NaCo using the angular differential imaging technique. By combining the constraints from direct imaging and radial velocity we derived the frequency of brown dwarfs around sound like stars in the 5 to 50 AU range.

Seminars are also held at JAC, CFHT, and IfA.
