Performance of the Gemini Planet Imager Non-Redundant Mask and spectroscopy of two close-separation binaries HR 2690 and HD 142527
Alexandra Z. Greenbaum, Anthony Cheetham, Anand Sivaramakrishnan +51
The Gemini Planet Imager (GPI) contains a 10-hole non-redundant mask (NRM), enabling interferometric resolution in complement to its coronagraphic capabilities. The NRM operates bo…
Automated data processing architecture for the Gemini Planet Imager Exoplanet Survey
Jason Wang, Marshall Perrin, Dmitry Savransky +49
The Gemini Planet Imager Exoplanet Survey (GPIES) is a multi-year direct imaging survey of 600 stars to discover and characterize young Jovian exoplanets and their environments. We…
Improving and Assessing Planet Sensitivity of the GPI Exoplanet Survey with a Forward Model Matched Filter
Jean-Baptiste Ruffio, Bruce Macintosh, Jason J. Wang +49
We present a new matched filter algorithm for direct detection of point sources in the immediate vicinity of bright stars. The stellar Point Spread Function (PSF) is first subtract…
Characterizing 51 Eri b from 1-5 m: a partly-cloudy exoplanet
Abhijith Rajan, Julien Rameau, Robert J. De Rosa +58
We present spectro-photometry spanning 1-5 m of 51 Eridani b, a 2-10 M planet discovered by the Gemini Planet Imager Exoplanet Survey. In this study, we present new…
Evidence that the Directly-Imaged Planet HD 131399 Ab is a Background Star
Eric L. Nielsen, Robert J. De Rosa, Julien Rameau +55
We present evidence that the recently discovered, directly-imaged planet HD 131399 Ab is a background star with non-zero proper motion. From new JHK1L' photometry and spectroscopy…
Constraints on the architecture of the HD 95086 planetary system with the Gemini Planet Imager
Julien Rameau, Eric L. Nielsen, Robert J. De Rosa +31
We present astrometric monitoring of the young exoplanet HD 95086 b obtained with the Gemini Planet Imager between 2013 and 2016. A small but significant position angle change is d…
