Spectral unmixing for exoplanet direct detection in hyperspectral data
Julien Rameau, Jocelyn Chanussot, Alexis Carlotti +2
The direct detection of exoplanets with high-contrast instruments can be boosted with high spectral resolution. For integral field spectrographs yielding hyperspectral data, this m…
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…
Revised Astrometric Calibration of the Gemini Planet Imager
Robert J. De Rosa, Meiji M. Nguyen, Jeffrey Chilcote +49
We present a revision to the astrometric calibration of the Gemini Planet Imager (GPI), an instrument designed to achieve the high contrast at small angular separations necessary t…
Asymmetries in adaptive optics point spread functions
Alexander Madurowicz, Bruce Macintosh, Vanessa P. Bailey +45
An explanation for the origin of asymmetry along the preferential axis of the PSF of an AO system is developed. When phase errors from high altitude turbulence scintillate due to F…
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…
Upgrading the Gemini Planet Imager: GPI 2.0
Jeffrey K. Chilcote, Vanessa P. Bailey, Rob De Rosa +10
The Gemini Planet Imager (GPI) is the dedicated high-contrast imaging facility, located on Gemini South, designed for the direct detection and characterization of young Jupiter mas…
