A Multiband Study of the HR 4796A Disk in the Optical Using MagAO-X

Jay K. Kueny, Alycia J. Weinberger, Zhe-Yu Daniel Lin +18

We present total intensity images of the debris disk around HR 4796A from observations spanning 2023 to 2025 with the Magellan extreme adaptive optics instrument (MagAO-X). We dete…

The spectral energy distribution of YSES 1 b and its circumplanetary disc

Michiel Darcis, Sebastiaan Y. Haffert, Tomas Stolker +18

Context. Direct imaging enables the characterisation of substellar companions on wide orbits. These objects provide a testbed for our formation theories; therefore, it is important…

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…

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…

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…

Challenge of direct imaging of exoplanets within structures: disentangling real signal from point source from background light

Jialin Li, Laird M. Close, Jared R. Males +19

The high contrast and spatial resolution requirements for directly imaging exoplanets requires effective coordination of wavefront control, coronagraphy, observation techniques, an…

Material Properties of Organic Liquids, Ices, and Hazes on Titan

Xinting Yu, Yue Yu, Julia Garver +5

Titan has a diverse range of materials in its atmosphere and on its surface: the simple organics that reside in various phases (gas, liquid, ice) and the solid complex refractory o…
