Title: Completing the follow-ups of the 300 stars International Deep Planet Survey

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 over the last year and we found a total of 250 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, 48 stars having 100 Jupiter-like planet candidates orbiting at less than 200AU still remain to be followed. We need follow-up observations to distinguish between true planets and background objects using a parallax and proper motion analysis. A statistical study of the actual sample and colour measurements of some candidates let us believe that there is a high probability that a few of the remaining candidates are true planets. Assuming good weather, this is the second to last IDPS proposal. A small proposal will be submitted for 2013A to complete the follow-ups for 5 stars that are not accessible in 2012B
