The JWST weather report: Unravelling the atmospheric variability of isolated worlds using principal component analysis
Merle A. Schrader, Johanna M. Vos, Evert Nasedkin +17
The paper uses principal component analysis on JWST/NIRSpec time‑series spectra of the brown dwarf SIMP‑0136 to identify two dominant patterns of variability, linking them to tempe…
On the Detectability of Volcanic Exo-Ios That May Fuel Auroras on Super-Jupiters
Brooke Kotten, Mary Anne Limbach, Johanna M. Vos +12
The paper evaluates whether JWST transit observations can detect volcanic exomoons around aurorally active super‑Jupiters, demonstrating feasibility for moons with mass ratios simi…
Disentangling auroral, cloud and magnetic spot driven variability in three early L-dwarfs with HST/WFC3
C. O'Toole, J. M. Vos, E. N. Nasedkin +5
Variability monitoring provides an unparalleled insight into the atmospheric processes of brown dwarfs and directly imaged exo-planets. Inhomogeneous clouds, aurorae and magnetic s…
Mapping the Cloud-Driven Atmospheric Dynamics & Chemistry of an Isolated Exoplanet Analog with Harmonic Signatures
Michael K. Plummer, Francis P. Cocchini, Peter A. Kearns +12
Young planetary-mass objects and brown dwarfs near the L/T spectral transition exhibit enhanced spectrophotometric variability over field brown dwarfs. Patchy clouds, auroral proce…
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…
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…
