Direct imaging of targets with radial velocity drifts from the HARPS and CORALIE surveys.

Using radial velocity data from our two planet-search surveys, CORALIE and HARPS, spanning over more than a decade, we get access to promising targets for direct imaging of substellar companions to solar-type stars. The observations are conducted on VLT/NACO using the angular differential imaging technique. With the help of the radial velocity information, a non-detection still yields strong constraints on the companion by giving a higher limit on mass and separation. This program is expected to detect long-period, massive, cold Jupiters and brown dwarfs. Data is being analyzed and preliminary results will be discussed in the poster.
