The Gemini Planet Imager (GPI), a coronagraphic adaptive optics instrument designed for spectroscopy of extrasolar planets, had first light in 2013. After five years, GPI has observed more than 500 stars, producing an extensive library of science images and associated telemetry that can be analyzed to determine performance predictors. We will present a summary of on-sky performance and lessons learned. The two most significant factors determining bright star contrast performance are atmospheric… Expand
Upgrading the Gemini planet imager: GPI 2.0
TLDR
The proposed upgrades which include a pyramid wavefront sensor, broadband low spectral resolution prisms and new apodized-pupil Lyot coronagraph designs all of which will enhance the current science capabilities while enabling new science programs are presented. Expand
Moving the Gemini planet imager to Gemini North: expectations and challenges
After more than 4 years of operation it’s expected that the Gemini Planet Imager (GPI) will move from Gemini South (GS) to the Gemini North (GN) telescope sometime in 2019. Though both telescopes areExpand
GPI 2.0: Upgrades to the IFS including new spectral modes
The Gemini Planet Imager (GPI) is a high-contrast imaging instrument designed to directly image and characterize exoplanets. GPI is currently undergoing several upgrades to improve performance. InExpand
A Deep Polarimetric Study of the Asymmetrical Debris Disk HD 106906
Located in the Lower Centaurus Crux group, HD 106906 is a young, binary stellar system. This system is unique among discovered systems in that it contains an asymmetrical debris disk, as well as anExpand
Information-theoretical Limits of Recursive Estimation and Closed-loop Control in High-contrast Imaging
A lower bound on unbiased estimates of wave front errors (WFEs) is presented for the linear regime of small perturbation and active control of a high-contrast region (dark hole). AnalyticalExpand

BAFFLES: Bayesian Ages for Field Lower-mass Stars
Age is a fundamental parameter of stars, yet in many cases ages of individual stars are presented without robust estimates of the uncertainty. We have developed a Bayesian framework, BAFFLES, toExpand
Debris Disk Results from the Gemini Planet Imager Exoplanet Survey's Polarimetric Imaging Campaign
We report the results of a ${\sim}4$-year direct imaging survey of 104 stars to resolve and characterize circumstellar debris disks in scattered light as part of the Gemini Planet Imager ExoplanetExpand
Direct Imaging Discovery of a Young Brown Dwarf Companion to an A2V Star
We present the discovery and spectroscopy of HIP 75056Ab, a companion directly imaged at a very small separation of 0.125 arcsec to an A2V star in the Scorpius-Centaurus OB2 association. OurExpand
Performance limits of adaptive-optics/high-contrast imagers with pyramid wavefront sensors
Advanced AO systems will likely utilise Pyramid wave-front sensors (PWFS) over the traditional Shack-Hartmann sensor in the quest for increased sensitivity, peak performance and ultimate contrast.Expand

Performance of the Gemini Planet Imager's adaptive optics system.
TLDR
The Gemini Planet Imager's adaptive optics subsystem was designed specifically to facilitate high-contrast imaging and science observations show that image quality can be improved with the use of both the spatially filtered wavefront sensor and linear-quadratic-Gaussian control of vibration. Expand
Gemini planet imager one button approach
TLDR
The Gemini Planet Imager is an “extreme” adaptive optics coronagraph system that is now on the Gemini South telescope in Chile and the sequencing of these systems both internally and externally through the observatory is described. Expand
First light of the Gemini Planet Imager
TLDR
Observations ofBeta Pictoris clearly detect the planet, Beta Pictoris b, in a single 60-s exposure with minimal postprocessing, and fitting the Keplerian orbit of Beta Pic b using the new position together with previous astrometry gives a factor of 3 improvement in most parameters over previous solutions.
