Scientific paper

The Gemini Planet imager is a next-generation planet-detection system for the Gemini Observatory. It combines a 1800-actuator adaptive optics system, an apodized-pupil Lyot coronagraph, ultrasmooth optics, a precision infrared interferometric wavefront sensor, and a infrared integral field spectrograph. It is predicted to achieve contrast >10^-7 around stars brighter than I=8 mag, allowing a comprehensive survey for Jovian-mass companions to moderate-age (<2 Gyr) field stars. It will also have a polarimetric mode for high sensitivity to circumstellar debris disks, and open a wide variety of adjunct science missions. I will discuss the GPI design, capabilities, and science drivers.
