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): A Gap-clearing Planet in a Multi-ringed Disk around the Young Solar-type Star WISPIT 2
Richelle F. van Capelleveen, Christian Ginski, Matthew A. Kenworthy +17
In the past decades several thousand exoplanet systems have been discovered around evolved, main-sequence stars, revealing a wide diversity in their architectures. To understand ho…
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…
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…
