Polarization aberrations in next-generation giant segmented mirror telescopes (GSMTs) I. Effect on the coronagraphic performance
Ramya M. Anche, Jaren N. Ashcraft, Sebastiaan Y. Haffert +8
Next-generation large segmented mirror telescopes are expected to perform direct imaging and characterization of Earth-like rocky planets, which requires contrast limits of $10^{-7…
Implicit electric field Conjugation: Data-driven focal plane control
S. Y. Haffert, J. R. Males, K. Ahn +11
Direct imaging of Earth-like planets is one of the main science cases for the next generation of extremely large telescopes. This is very challenging due to the star-planet contras…
HIP 67506 C: MagAO-X Confirmation of a New Low-Mass Stellar Companion to HIP 67506 A
Logan A. Pearce, Jared R. Males, Sebastiaan Y. Haffert +17
We report the confirmation of HIP 67506 C, a new stellar companion to HIP 67506 A. We previously reported a candidate signal at 2/D (240~mas) in L in MagAO/Clio imagi…
Experimental Trials With The Optical Differentiation Wavefront Sensor For Extended Objects
Meghan Farris O'Brien, Sebastiaan Y. Haffert, Joseph D. Long +4
Commonly used wavefront sensors, the Shack Hartmann wavefront sensor and the pyramid wavefront sensor, for example, have large dynamic range or high sensitivity, trading one regime…
XPipeline: Starlight subtraction at scale for MagAO-X
Joseph D. Long, Jared R. Males, Sebastiaan Y. Haffert +15
MagAO-X is an extreme adaptive optics (ExAO) instrument for the Magellan Clay 6.5-meter telescope at Las Campanas Observatory in Chile. Its high spatial and temporal resolution can…
Advanced wavefront sensing and control demonstration with MagAO-X
Sebastiaan Y. Haffert, Jared R. Males, Kyle Van Gorkom +13
The search for exoplanets is pushing adaptive optics systems on ground-based telescopes to their limits. Currently, we are limited by two sources of noise: the temporal control err…
