Simulation results for Robo-AO-2 using HAPA: a wavefront sensing technique for improving the adaptive optics correction of fainter stars

Ruihan Zhang, Christoph Baranec, Marcos A. van Dam +3

Direct imaging of exoplanets allows us to measure positions and chemical signatures of exoplanets. Given the limited resources for space observations where the atmosphere is absent…

Commissioning results from the Robo-AO-2 facility for rapid visible and near-infrared AO imaging

Christoph Baranec, James Ou, Reed Riddle +16

We installed the next-generation automated laser adaptive optics system, Robo-AO-2, on the University of Hawaii 2.2-m telescope on Maunakea in 2023. We engineered Robo-AO-2 to deli…
