The final design of GMagAO-X: high-contrast imaging at first-light of the GMT
Jared R. Males, Laird M. Close, Sebastiaan Y. Haffert +13
GMagAO-X will be the first-light high-contrast imager on the 25 m Giant Magellan Telescope. The driving science case for GMagAO-X is characterization of the atmospheres of nearby r…
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…
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-…
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…
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 proto…
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 sensitiv…
