Constraining the Evolution and Migration of Young Giant Planets
Abstract
The presence of giant planets interior to the ice lines of Sun-like stars indicates that inward orbital migration is a common phenomenon. However, the processes by which these gas giants arrived at their present-day locations are poorly constrained because previous radial velocity surveys have largely avoided young stars. We are carrying out a large precision RV survey of intermediate-age (50-250 Myr) GK dwarfs with the Habitable Zone Planet Finder (HPF), a stabilized high resolution, near-infrared spectrograph located at the Hobbly-Eberly Telescope. The science goals of this program are to determine the timescale and dominant physical mechanism of giant planet migration. We will present the survey design and initial results, including the first measurements of stellar jitter at J-band for a large sample of young Sun-like stars.
