The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future

Niall Whiteford, Jacqueline K. Faherty, Ben Burningham +123

JWST defines a new era for the data-driven approach of retrieval modelling, which has become a cornerstone tool for the statistical inference of exoplanetary and brown dwarf proper…

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…

Evidence for a Peak at 0.3 in the Eccentricity Distribution of Typical Super-Jovian Exoplanets

Sarah Blunt, Jason Wang, Ruth Murray-Clay +3

In this study, we compute completeness-corrected occurrence rates of giant exoplanets as a function of mass, semimajor axis, and eccentricity, using the approximately uniform Calif…

A second planetesimal collision in the Fomalhaut system

Paul Kalas, Jason J. Wang, Maxwell A. Millar-Blanchaer +7

The nearby star Fomalhaut is orbited by a compact source, Fomalhaut b, which has previously been interpreted as either a dust-enshrouded exoplanet or a dust cloud generated by the…

Characterizing the Time Variability of 2M1207 A+b with JWST NIRSpec/PRISM

Arthur D. Adams, Yifan Zhou, Gabriel Dominique-Marleau +13

We present JWST NIRSpec/PRISM IFU time-resolved observations of 2M1207 A and b (TWA 27), a Myr binary system consisting of a K sub-stellar primary hosting a $…

YSES 2b is a background star: Differential astrometric M-dwarf measurements in time

Matthew Kenworthy, Tomas Stolker, Jens Kammerer +13

We wish to confirm the nature of YSES 2b, a purportedly faint companion of the young star YSES 2. We used on-sky observations from SPHERE and GRAVITY to measure the astrometric pos…

Follow-Up Exploration of the TWA 7 Planet-Disk System with JWST NIRCam

Katie A. Crotts, Aarynn L. Carter, Kellen Lawson +39

The young M-star TWA 7 hosts a bright and near face-on debris disk, which has been imaged from the optical to the submillimeter. The disk displays multiple complex substructures su…

Differentiating Formation Models with New Dynamical Masses for the PDS 70 Protoplanets

David Trevascus, Sarah Blunt, Valentin Christiaens +22

Hot- and cold-start planet formation models predict differing luminosities for the young, bright planets that direct imaging surveys are most sensitive to. However, precise mass es…

The Giant Accreting Protoplanet Survey (GAPlanetS) -- Results from a Six Year Campaign to Image Accreting Protoplanets

Katherine B. Follette, Laird M. Close, Jared R. Males +20

Accreting protoplanets represent a window into planet formation processes. We report Hα differential imaging results from the deepest and most comprehensive accreting protoplanet s…
