Silicate Clouds, SiO, and Molecular Trends across the L-T Sequence: A JWST/MIRI LRS Spectral Library of Brown Dwarfs
Sam Barber, Stanimir Metchev, Genaro Suárez +12
We present the results of a survey program with JWST's MIRI LRS that obtained 514 m R~100 spectra of twenty-three L0T6 dwarfs. This spectral type range spans the formation…
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…
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…
Clouds with a silicate lining: Using JWST spectra to probe atmospheric diversity in young AB Dor L dwarfs
M. B. Lam, J. M. Vos, G. Suárez +13
We present the first full JWST NIRSpec Prism and MIRI LRS 0.6 - 14 m (R ~ 100) spectra and analysis of five ~ 133 Myr L dwarf members of the AB Doradus moving group and one pro…
Twinkle Twinkle Little Star, Roman Sees Where You Are: Predicting Exoplanet Transit Yields in the Rosette Nebula with the Nancy Grace Roman Space Telescope
Ritvik Sai Narayan, Melinda Soares-Furtado, Mary Anne Limbach +3
Young stars host only a small fraction of the known exoplanet population because their photometric variability, magnetic activity, and frequent placement in dense, poorly-resolved…
