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…

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…

1 to 2.4 micron Near-IR spectrum of the Giant Planet Pictoris b obtained with the Gemini Planet Imager

Jeffrey Chilcote, Laurent Pueyo, Robert J. De Rosa +61

Using the Gemini Planet Imager (GPI) located at Gemini South, we measured the near-infrared (1.0-2.4 micron) spectrum of the planetary companion to the nearby, young star Picto…
