Jess A. Johnson, Amali Vaz, Manny Montoya +23
The MMT Adaptive Optics exoPlanet Characterization System (MAPS) is a comprehensive update to the first generation MMT adaptive optics system (MMTAO), designed to produce a facilit…
Phase-Induced Amplitude Apodization Complex Mask Coronagraph (PIAACMC) on-sky demonstration with MagAO-X
Elena Tonucci, Sebastiaan Haffert, Warren Foster +18
Advancing the technological development of small inner working angle (IWA) coronagraphs is essential to enabling high-contrast imaging of temperate exoplanets with future extremely…
The Three-Sided PyramidWavefront Sensor. I. Simulations and Analysis for Astronomical Adaptive Optics
Lauren Schatz, Jared R. Males, Carlos Correia +11
For ExAO instruments for the Giant Segmented Mirror Telescopes (GSMTs), alternative architectures of WFS are under consideration because there is a tradeoff between detector size,…
Sensor fusion on MagAO-X: real time vibration control using accelerometers
Parker T. Johnson, Jared R. Males, Povilas Palunas +16
Mechanical vibrations are a significant source of residual wavefront error (WFE) in adaptive optics (AO) systems, limiting the performance of high-contrast imaging instruments. We…
Making the unmodulated Pyramid wavefront sensor smart. Closed-loop demonstration of neural network wavefront reconstruction with MagAO-X
Rico Landman, Sebastiaan Haffert, Jared Males +12
Almost all current and future high-contrast imaging instruments will use a Pyramid wavefront sensor (PWFS) as a primary or secondary wavefront sensor. The main issue with the PWFS…
Magellan Adaptive Optics Imaging of PDS 70: Measuring the Mass Accretion Rate of a Young Giant Planet within a Gapped Disk
Kevin Wagner, Katherine B. Follette, Laird M. Close +11
PDS 70b is a recently discovered and directly imaged exoplanet within the wide (40 au) cavity around PDS 70 (Keppler et al. 2018, Müller et al. 2018). Ongoing accretion o…
