Comparison of Phase-Unwrapping Methods for Adaptive Optics Wavefront Sensing
D. Angelica Huerta, Justin R. Crepp, Caleb G. Abbott +1
Advanced wavefront sensors (WFS) are essential for enabling new science cases for telescopes that utilize adaptive optics (AO) systems. While complex field WFS -- those that estima…
Jitter Sensing and Control for Multi-Plane Phase Retrieval
Caleb G. Abbott, Justin R. Crepp, Brian Sands
The family of multi-plane phase retrieval sensors, such as the curvature and nonlinear curvature wavefront sensors (WFS), contain tip/tilt information embedded in their signals. We…
Planet Masses, Radii, and Orbits from NASA's K2 Mission
Andrew W. Howard, Evan Sinukoff, Sarah Blunt +50
We report the masses, sizes, and orbital properties of 86 planets orbiting 55 stars observed by NASA's K2 Mission with follow-up Doppler measurements by the HIRES spectrometer at t…
