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…
