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…
Constraining the Orbit and Mass of epsilon Eridani b with Radial Velocities, Hipparcos IAD-Gaia DR2 Astrometry, and Multi-epoch Vortex Coronagraphy Upper Limits
Jorge Llop-Sayson, Jason J. Wang, Jean-Baptiste Ruffio +30
~Eridani is a young planetary system hosting a complex multi-belt debris disk and a confirmed Jupiter-like planet orbiting at 3.48 AU from its host star. Its age and architectur…
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…
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…
Characterization of lemniscate atmospheric aberrations in Gemini Planet Imager data
Alexander Madurowicz, Bruce A. Macintosh, Jean-Baptiste Ruffio +5
A semi analytic framework for simulating the effects of atmospheric seeing in Adaptive Optics systems on an 8-m telescope is developed with the intention of understanding the origi…
