The JWST weather report: Unravelling the atmospheric variability of isolated worlds using principal component analysis

Merle A. Schrader, Johanna M. Vos, Evert Nasedkin +17

Brown dwarf variability directly probes atmospheric dynamics beyond the Solar System, and recent JWST time-resolved spectroscopy has opened a new window into these processes. Princ…

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…

On the Detectability of Volcanic Exo-Ios That May Fuel Auroras on Super-Jupiters

Brooke Kotten, Mary Anne Limbach, Johanna M. Vos +12

Studies suggest Jupiter's aurorae are supplied with plasma from volcanic outflows on the planet's innermost moon, Io. Repeating bursts of radio emission thought to trace massively…

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…

The Diversity of Cold Worlds: Age and Characterization of the Exoplanet COCONUTS-2b

Rocio Kiman, Charles A. Beichman, Azul Ruiz Diaz +19

Studying cold brown dwarfs is key to understanding the diverse characteristics of cold giant exoplanets atmospheres. COCONUTS-2, is a wide binary system composed of a T9 brown dwar…

Discovery of the Second Y+Y Dwarf Binary System: CWISEP J193518.59-154620.3

Matthew De Furio, Jacqueline Kelly Faherty, Daniella C. Bardalez Gagliuffi +10

We present the discovery of a companion to the Y-dwarf, CWISEP J193518.59-154620.3, the second Y-Y dwarf binary detected to date. Y-dwarfs are the coldest known free-floating objec…

Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system

Kielan K. W. Hoch, Melanie Rowland, Simon Petrus +26

Young exoplanets provide a critical link between understanding planet formation and atmospheric evolution. Direct imaging spectroscopy allows us to infer the properties of young, w…

The JWST Weather Report: retrieving temperature variations, auroral heating, and static cloud coverage on SIMP-0136

Evert Nasedkin, Merle Schrader, Johanna M. Vos +15

SIMP-0136 is a T2.5 brown dwarf whose young age (~Myr) and low mass (~M) make it an ideal analogue for the directly imaged exoplanet population. With…

The JWST Weather Report from the Isolated Exoplanet Analog SIMP 0136+0933: Pressure-Dependent Variability Driven by Multiple Mechanisms

Allison M. McCarthy, Johanna M. Vos, Philip S. Muirhead +17

Isolated planetary-mass objects share their mass range with planets but do not orbit a star. They lack the necessary mass to support fusion in their cores and thermally radiate the…
