Abstract

Direct imaging searches for exoplanets are sensitive to wide orbit planets and provide complementary information on the exoplanet population compared to indirect detection techniques. Recent high-contrast imaging has revealed a multiple planet system orbiting the young, dusty A-star HR 8799. The three planets are located projected separations of 24-68 AU and have masses estimated to be 7-10 times the mass of Jupiter. The discovery of massive planets at the orbital radii around HR 8799 system and other recently imaged exoplanets present important test cases for models of planet formation and evolution. Ongoing imaging surveys and upcoming instrument projects will further characterize the population of outer giant planets.
