Photometric Variability and Rotation of Beta Pictoris b from JWST NIRCam Coronagraphic Imaging
Yifan Zhou, Beth A. Biller, Aarynn L. Carter +30
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 c…
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
The paper reports the direct imaging discovery of a third giant exoplanet, β Pictoris d, using VLT/ERIS and archival JWST/NIRCam and VLT/SPHERE data, and characterizes its orbit, t…
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…
