Daytime calibration and testing of the Keck All sky Precision Adaptive Optics Tomography System
Avinash Surendran, Jacques R. Delorme, Carlos M. Correia +12
The development of the Keck All sky Precision Adaptive optics (KAPA) project was initiated in September 2018 to upgrade the Keck I adaptive optics (AO) system to enable laser tomog…
AIROPA III: Testing Simulated and On-Sky Data
Paolo Turri, Jessica R. Lu, Gunther Witzel +6
Adaptive optics images from the W. M. Keck Observatory have delivered numerous influential scientific results, including detection of multi-system asteroids, the supermassive black…
Predictive wavefront control on Keck II adaptive optics bench: on-sky coronagraphic results
Maaike A. M. van Kooten, Rebecca Jensen-Clem Sylvain Cetre, Sam Ragland +3
The behavior of an adaptive optics (AO) system for ground-based high contrast imaging (HCI) dictates the achievable contrast of the instrument. In conditions where the coherence ti…
On-sky reconstruction of Keck Primary Mirror Piston Offsets using a Zernike Wavefront Sensor
Maaike A. M. van Kooten, Sam Ragland, Rebecca Jensen-Clem +3
The next generation of large ground- and space-based optical telescopes will have segmented primary mirrors. Co-phasing the segments requires a sensitive wavefront sensor capable o…
Retrieving the C and O Abundances of HR 7672~AB: a Solar-Type Primary Star with a Benchmark Brown Dwarf
Ji Wang, Jared R. Kolecki, Jean-Baptiste Ruffio +30
A benchmark brown dwarf (BD) is a BD whose properties (e.g., mass and chemical composition) are precisely and independently measured. Benchmark BDs are valuable in testing theoreti…
