Abstract
The International Deep Planet Survey has already provided exciting results with the first detection of a four-planet system orbiting the young star HR 8799. Over the course of the IDPS we have surveyed 300 stars, using several AO systems such as ALTAIR/NIRI (Gemini North), NICI (Gemini South), NIRC2 (Keck), and NACO (VLT). The entire campaign was fully reduced and analyzed and we found a total of 350 planet candidates at less than 200AU projected separation. Using our own data as well as archive data from other programs, we have already confirmed most of the candidates as background objects. However, 7 to 9 stars (depending on the completion of our 2013B program) have 12 Jupiter-like planets at less than 200 AU that need a second epoch for confirmation. We need follow-up observations to distinguish between true planets and background objects using a parallax and proper motion analysis. Given the position of the targets in the sky and the colour measurements of some candidates, we believe that there is a high probability that a few of the remaining candidates are true exoplanets.
