Optical design and polarimetric performance of a SmallSat UV polarimeter to study interstellar dust: PUFFINS
Ramya M Anche, Hyukmo Kang, Kyle Van Gorkom +19
The Polarimetry in the Ultraviolet to Find Features in INterStellar dust (PUFFINS) is a SmallSat mission concept designed to obtain ultraviolet (UV) spectropolarimetric observation…
The Space Coronagraph Optical Bench (SCoOB): 7. design, fabrication, and first light for a self-coherent camera
Kevin Derby, Kian Milani, Grace C. Hathaway +10
The 2020 Decadal Survey on Astronomy and Astrophysics tasked future space observatories with the goal of detecting and characterizing a large sample of Earth-like exoplanets. To ac…
The Space Coronagraph Optical Bench (SCoOB): 6. demonstration of Lyot low order wavefront control combined with high order wavefront control using a vortex coronagraph
Kian Milani, Kyle Van Gorkom, Chris B. Mendillo +6
To reach and maintain high contrast levels, coronagraph instruments will require a combination of low-order and high-order wavefront control techniques to correct for dynamic wavef…
Five New Sirius-Like White Dwarf + Main Sequence Star Systems with MagAO-X
Logan A. Pearce, Jared R. Males, Sebastiaan Y. Haffert +20
Most known white dwarfs in multiple systems with main sequence stars have been discovered with M-type companions, because the white dwarf causes detectable UV excess and bluer colo…
A planetary-mass candidate imaged in the Young Suns Exoplanet Survey
Pengyu Liu, Matthew A. Kenworthy, Beth A. Biller +26
Directly imaged exoplanets in wide orbits challenge current gas giant formation theories. They need to form quickly and acquire enough material before the disk dissipates, which ca…
Making the unmodulated pyramid wavefront sensor smart II. First on-sky demonstration of extreme adaptive optics with deep learning
R. Landman, S. Y. Haffert, J. D. Long +17
Pyramid wavefront sensors (PWFSs) are the preferred choice for current and future extreme adaptive optics (XAO) systems. Almost all instruments use the PWFS in its modulated form t…
Performance predictions and contrast limits for an ultraviolet high contrast imaging testbed
Kyle Van Gorkom, Ramya M. Anche, Christopher B. Mendillo +7
NASA's Habitable Worlds Observatory (HWO) concept and the 2020 Decadal Survey's recommendation to develop a large space telescope to "detect and characterize Earth-like extrasolar…
Three Years of High-Contrast Imaging of the PDS 70 b and c Exoplanets at Hα with MagAO-X: Evidence of Strong Protoplanet Hα Variability and Circumplanetary Dust
Laird M. Close, Jared R. Males, Jialin Li +23
We present 3 years of high-contrast imaging of the PDS 70 b and c accreting protoplanets with the new extreme AO system MagAO-X as part of the MaxProtoPlanetS survey of H protop…
Phasing the Giant Magellan Telescope: Lab Experiments and First On-sky Demonstration
Maggie Y. Kautz, Sebastiaan Y. Haffert, Laird M. Close +21
The large apertures of the upcoming generation of Giant Segmented Mirror Telescopes will enable unprecedented angular resolutions that scale as /D and higher sensitivi…
Polarization aberrations in next-generation Giant Segmented Mirror Telescopes (GSMTs). II. Influence of segment-to-segment coating variations on high-contrast imaging and polarimetry
Jaren N. Ashcraft, Ramya M. Anche, Sebastiaan Y. Haffert +8
Direct exo-Earth imaging is a key science goal for astronomy in the next decade. This ambitious task imposes a target contrast of ~10^-7 at wavelengths from I to J-band. In our pri…
Real-time control and data standardization on various telescopes and benches
Nour Skaf, Rebecca Jensen-Clem, Aaron Hunter +19
Real-time control (RTC) is pivotal for any Adaptive Optics (AO) system, including high-contrast imaging of exoplanets and circumstellar environments. It is the brain of the AO syst…
