Estimating effective wind speed from Gemini Planet Imager's adaptive optics data using covariance maps
Daniel M. Levinstein, Saavidra Perera, Quinn M. Konopacky +4
The Earth's turbulent atmosphere results in speckled and blurred images of astronomical objects when observed by ground based visible and near-infrared telescopes. Adaptive optics…
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…
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…
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…
HD 165054: an astrometric calibration field for high-contrast imagers in Baade's Window
Meiji M. Nguyen, Robert J. De Rosa, Jason J. Wang +51
We present a study of the HD 165054 astrometric calibration field that has been periodically observed with the Gemini Planet Imager. HD 165054 is a bright star within Baade's Windo…
