Gemini Planet Imager Extra Solar Survey 

The GPIES Campaign is the winning proposal in the CfP for Campaign observations with GPI. It was awarded 890h over six semesters starting in 2014B and concluded in semester 2018B.

GPIES Campaign Executive summary

The Gemini Planet Imager (GPI) was built as a survey instrument to directly detect planets and image debris disks. Our survey will use GPI to produce the first-ever robust census of giant planet populations in the 5-50 AU range, allowing us to

  1. formation pathways of Jovian planets
  2. early dynamical evolution of systems, including migration mechanisms and the interaction with disks and belts of debris
  3. gap between Jupiter and the brown dwarfs with the first examples of cool planetary atmospheres.

The only way to achieve robust and reliable statistical results is with a single coherent survey, with uniform and well-articulated selection criteria. We will observe 600 stars spanning spectral types A-M. We will use published young association catalogs and a proprietary list – the result of thousands of hours of telescope observations in preparation for GPI—that adds several hundred new young (<100 Myr, <75 and adolescent (<300 Myr, <35 stars. The latter, closer than the known young associations, allow our survey to probe the 5 AU ice line. Monte Carlo simulations of populations around these stars allow us to optimize the survey strategy for maximum statistical yield. The range of separations studied by GPI is completely inaccessible to Doppler and transit techniques (even with Kepler—a new window into planet formation.

this survey will discover approximately 50 increasing the number of images by an order of magnitude, enough for statistical investigation. The survey will deliver:

  1. A catalog of —the principal legacy of this campaign—released for follow-up to the Gemini community within 18 months of observation
  2. For a subset of 10 planets, a library of high-SNR GPI spectra at all 5 bands to calibrate temperature and gravity indicators
  3. For each planet, estimated effective temperatures and luminosities from GPI spectrophotometry, and semi-major axis estimates from orbital motion
  4. Empirical measurements of the number of young planets as a function of mass, semi-major axis, and stellar mass with the same precision as Doppler giant-planet surveys
  5. An estimated eccentricity distribution of a subset of planets sufficient to distinguish different dynamical evolutionary states at the 3-5 sigma level
  6. 6. Snapshot images of those stars in the survey predicted to have detectable debris disks
  7. High-SNR images of all debris disks showing planet-induced structure
  8. An automated data pipeline to process images and recover calibrated astrometry and photometry
  9. A public catalog containing all reduced images, recovered planetary properties, and detection limits

The large sample will for the first time match the statistical power of extant studies of planets using indirect techniques. GPI spectroscopy will reveal atmospheric conditions and thermal history, thereby calibrating atmosphere and accretion models. The statistical properties of the distributions will arbitrate between various formation and migration scenarios.
