Stray and Scattered Light Considerations in a Non-contiguous Array of Commercial CMOS Sensors in a Space Mission

Maggie Y. Kautz, Douglas Kelly, Heejoo Choi +6

Recent advances in CMOS technology have potential to significantly increase the performance, at low-cost, of an astronomical space telescope. Arrays of sensors in space missions ar…

Wide Separation Planets In Time (WISPIT): Discovery of a Gap H Protoplanet WISPIT 2b with MagAO-X

Laird M. Close, Richelle F. van Capelleveen, Gabriel Weible +34

Excellent (<25 mas) H images of the star TYC 5709-354-1 led to the discovery of a rare H protoplanet. This star was discovered by the WISPIT survey to have a large multi-ri…

Discovery of H Emission from a Protoplanet Candidate Around the Young Star 2MASS J16120668-3010270 with MagAO-X

Jialin Li, Laird M. Close, Feng Long +32

2MASS J16120668-3010270 (hereafter 2MJ1612) is a young M0 star that hosts a protoplanetary disk in the Upper Scorpious star-forming region. Recent ALMA observations of 2MJ1612 show…

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…

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…
