Abstract
Following our discovery of the HR 8799 3-planet system at Gemini, we propose to use the simultaneous methane on/off imaging capabilities of NICI to constrain the presence of methane in the planets of this system. We also propose to pursue, with NICI, our ongoing volume-limited (<55 pc) deep AO/ADI A- & F-type star IDPS survey in the South and to acquire new unpublished southern young & close FGKM stars. The main goal of this proposal is to improve the number of observed stars of all spectral types to achieve a survey of ~250 stars (including the GDPS sample) and to derive new and improved statistics on the frequency of planet around star of various masses. We will have, for the first time, a broader picture of the population of massive planets at large semi-major axes around a wide range of stellar mass.
