Title: Planet-drive spiral arms in SAO 206462: a direct test of dynamical model predictions

Abstract: We propose to make the first-ever direct connection between a newborn exoplanet and the its gravitationally-induced structures in a circumstellar gaseous disk using Gemini/GPI. NIR polarized scattered light observations have discovered two large scale spiral arms in the Herbig system SAO 206462. Recently, we proposed a disk-planet interaction model to explain the morphology of the arms of the system. The existence of a ~10 Jupiter-mass planet at 0.7 arcsec from the center is predicted in the model. We propose to to search for and confirm this putative planet using GPI.
