The Gemini Planet Imager Exoplanet Survey
Lead:Paul Kalas, James Graham
The Gemini Planet Imager (GPI) is an advanced science instrument that exploits the latest generation of adaptive optics technology, coronagraphy and detectors. We commissioned GPI at the Gemini South telescope in Chile in 2014 and finished a five-year survey for exoplanets called GPIES (GPI Exoplanet Survey). Among the many discoveries were the planet 51 Eri b and many dusty debris disks, published in over 30 peer-reviewed manuscripts. GPI will be upgraded and installed on Gemini North in Hawaii in 2025.
