Photometric Variability and Rotation of Beta Pictoris b from JWST NIRCam Coronagraphic Imaging
Yifan Zhou, Beth A. Biller, Aarynn L. Carter +28
We report the detection of photometric variability in the directly imaged super-Jupiter Pictoris b. Using JWST NIRCam dual-band coronagraphic imaging, we conducted a 16-hour co…
Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
We report the direct imaging discovery of a third exoplanet in the Pictoris system. We detect Pictoris d ( Pic d) in non-coronagraphic observations obtained with VLT/ERI…
Building a Roadmap for Hubble Science into the 2030s: Revealing Atmospheric Structure and Evolution in Substellar Worlds Using HST
Allison M. McCarthy, Merle A. Schrader, Johanna M. Vos +15
Substellar objects occupy a unique place in our universe, bridging the gap between the smallest stars and the largest planets, and serving as powerful laboratories for understandin…
Stellar separation shapes spin-orbit alignment in visual binaries
Michael Poon, Dang Pham, Marta L. Bryan +2
Stellar binaries may form through several formation pathways, including disk or core fragmentation. Their spin-orbit angles are a signature of formation, although individual measur…
Early evidence for isotropic planetary obliquities in young super-Jupiter systems
Michael Poon, Marta L. Bryan, Hanno Rein +3
This decade has seen the first measurements of extrasolar planetary obliquities, characterizing how an exoplanet's spin axis is oriented relative to its orbital axis. These measure…
Continued Photometric Monitoring Supports Long-Term Dynamical Evolution in the Young Binary Star-Disk System KH 15D
Luke Lamitina, Lynne Hillenbrand, Michael Poon
We present photometric time series data spanning 2018-2024 that show the effects of temporal dynamics in the binary system KH 15D, a member of the NGC 2264 star forming region. Thi…
A potential exomoon from the predicted planet obliquity of Pictoris b
Michael Poon, Hanno Rein, Dang Pham
Planet obliquity is the alignment or misalignment of a planet spin axis relative to its orbit normal. In a multiplanet system, this obliquity is a valuable signature of planet form…
Leaning Sideways: VHS 1256-1257 b is a Super-Jupiter with a Uranus-like Obliquity
Michael Poon, Marta L. Bryan, Hanno Rein +4
We constrain the angular momentum architecture of VHS J125601.92-125723.9, a 140 20 Myr old hierarchical triple system composed of a low-mass binary and a widely-separated pl…
Two Candidate KH 15D-like Systems from the Zwicky Transient Facility
Wei Zhu, Klaus Bernhard, Fei Dai +8
KH 15D contains a circumbinary disk that is tilted relative to the orbital plane of the central binary. The precession of the disk and the orbital motion of the binary together pro…
