GPI 2.0 : Optimizing reconstructor performance in simulations and preliminary contrast estimates
Alexander Madurowicz, Bruce Macintosh, Lisa Poyneer +12
During its move from the mountaintop of Cerro Pachon in Chile to the peak of Mauna Kea in Hawaii, the Gemini Planet Imager will make a pit stop to receive various upgrades, includi…
GPI 2.0: Upgrades to the IFS including new spectral modes
Mary Anne Limbach, Jeffrey Chilcote, Quinn Konopacky +9
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…
Gemini Planet Imager Spectroscopy of the Dusty Substellar Companion HD 206893 B
K. Ward-Duong, J. Patience, K. Follette +55
We present new near-infrared Gemini Planet Imager (GPI) spectroscopy of HD 206893 B, a substellar companion orbiting within the debris disk of its F5V star. The , , , and…
Moderate-Resolution -Band Spectroscopy of Substellar Companion Andromedae b
Kielan K. Wilcomb, Quinn M. Konopacky, Travis S. Barman +5
We present moderate-resolution () band spectra of the "super-Jupiter," Andromedae b. The data were taken with the OSIRIS integral field spectrograph at Keck Obse…
Multiband Polarimetric Imaging of HR 4796A with the Gemini Planet Imager
Pauline Arriaga, Michael P. Fitzgerald, Gaspard Duchêne +49
HR4796A hosts a well-studied debris disk with a long history due to its high fractional luminosity and favorable inclination lending itself well to both unresolved and resolved obs…
The Gemini Planet Imager view of the HD 32297 debris disk
Gaspard Duchene, Malena Rice, Justin Hom +60
We present new -band scattered light images of the HD 32297 edge-on debris disk obtained with the Gemini Planet Imager (GPI). The disk is detected in total and polarized intensi…
