The JWST Sub-Jupiters Survey: Direct Imaging Discovery of a Giant Planet and a Debris Disk Around the Young M-dwarf RX J0534.0-0221

Rodrigo Ferrer-Chavez, Jason J. Wang, Kevin Wagner +47

We present the discovery of RX J0534.0-0221 b, a giant planet orbiting an M-dwarf star in the Pictoris moving group. RX J0534 was originally observed with JWST/NIRCam in the F4…

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…

Sensitivity to Sub-Io-sized Exosatellite Transits in the MIRI LRS Lightcurve of the Nearest Substellar Worlds

Andrew Householder, Mary Anne Limbach, Beth Biller +20

JWST's unprecedented sensitivity enables precise spectrophotometric monitoring of substellar worlds, revealing atmospheric variability driven by mechanisms operating across differe…

Global weather map reveals persistent top-of-atmosphere features on the nearest brown dwarfs

Xueqing Chen, Beth A. Biller, Johanna M. Vos +10

Brown dwarfs and planetary-mass companions display rotationally modulated photometric variability, especially those near the L/T transition. This variability is commonly attributed…

Identifying and Fitting Eclipse Maps of Exoplanets with Cross-Validation

Mark Hammond, Neil T. Lewis, Sasha Boone +10

Eclipse mapping uses the shape of the eclipse of an exoplanet to measure its two-dimensional structure. Light curves are mostly composed of longitudinal information, with the latit…

Observability of Forming Planets and their Circumplanetary Disks IV. -- with JWST & ELT

Xueqing Chen, Judit Szulágyi

To understand the potential for observing forming planets and their circumplanetary disks (CPDs) with JWST and ELT, we created mock observations from 3D radiative hydrodynamic simu…
