SUMMARY The Gemini Planet Imager Exoplanet Survey (GPIES) has observed approximately 17% of the 600 targets in its 890 hour campaign to directly image young, massive exoplanets about nearby stars. We present an update of the pre-survey performance simulations using GPI's on-sky performance data in the form of post-processed, angular separation-dependent(More)
We have spatially resolved five debris disks (HD 30447, HD 35841, HD 141943, HD 191089, and HD 202917) for the first time in near-infrared scattered light by reanalyzing archival Hubble Space Telescope (HST)/NICMOS coronagraphic images obtained between 1999 and 2006. One of these disks (HD 202917) was previously resolved at visible wavelengths using the(More)
We report high-cadence time-series photometry of the recently-discovered transiting exoplanet system HD 17156, spanning the time of transit on UT 2007 October 1, from three separate observatories. We present a joint analysis of our photometry, previously published radial velocity measurements, and times of transit center for 3 additional events. Adopting(More)
