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…
The ESO SupJup Survey XI. Atmospheric properties of six isolated M- and L-type dwarfs with CRIRES+
C. R. Malcolm, N. Grasser, I. A. G. Snellen +9
The distinct formation pathways of brown dwarfs and giant exoplanets may be encoded in their atmospheric composition. We present atmospheric retrievals for six isolated brown dwarf…
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…
Oxygen and nitrogen isotopologues on cold COCONUTS-2b observed with MIRI/MRS
H. Kühnle, E. C. Matthews, P. Mollière +12
Linking the composition of gas giant planets to their formation paths has long been a goal in exoplanet science. Especially, cold gas giants with temperatures below 500K have…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems. VII. Molecular Mapping Performance with JWST/MIRI MRS: VHS 1256 b as a case study
Mathilde Mâlin, Anthony Boccaletti, Benjamin Charnay +29
VHS 1256 b was the first planetary-mass companion to be observed with the James Webb Space Telescope's Mid-Infrared Instrument (JWST/MIRI) using the Medium-Resolution Spectrometer…
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…
