A Jupiter-like radio aurora in the L3.5 dwarf LSPM J0036+1821
D. Martín-Carrero, J. B. Climent, P. A. Miles-Páez +6
Ultracool dwarfs exhibit radio emission revealing strong magnetic fields and complex magnetospheric processes. Their auroral emission resembles that observed in magnetized Solar Sy…
Time-resolved JWST Retrieval Analysis of the Coldest Brown Dwarf: Temperature and Chemical Variations in WISE 0855-07
Harshil Kothari, Caroline V. Morley, Brittany E. Miles +12
WISE J0855-07 is the coldest known brown dwarf (estimated Teff~250 K), offering a rare opportunity to probe atmospheric physics in the temperature and mass regime that overlaps dir…
Water Cloud and Chemical Modulations in the Coldest Brown Dwarf
Brittany E. Miles, James Mang, Caroline V. Morley +24
We present high signal-to-noise, medium resolution (R ~ 1000), time-series JWST/NIRSpec spectra of WISE 0855 (265K), the coldest known brown dwarf. Medium resolution, time-series s…
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 +9
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
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…
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 prob…
Tempawral: A Time-Resolved Retrieval Framework for Variable Brown Dwarfs and Exoplanets
Fei Wang, Ben Burningham, Stuart Littlefair +4
Brown dwarfs and exoplanets are thought to host complex atmospheric phenomena such as clouds, storms, and chemical heterogeneity, akin to weather patterns on Earth. These features…
A Deep Search for Exomoons Around WISE 0855 With JWST
Mikayla J. Wilson, Mary Anne Limbach, Andrew J. Skemer +11
JWST is collecting time-series observations of many free-floating planets (FFPs) to study their weather, but these light curves are the ideal datasets to search for exomoons that t…
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…
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…
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…
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…
Protosolar D-to-H abundance and one part-per-billion PH in the coldest brown dwarf
Melanie J. Rowland, Caroline V. Morley, Brittany E. Miles +24
The coldest Y spectral type brown dwarfs are similar in mass and temperature to cool and warm (200 -- 400 K) giant exoplanets. We can therefore use their atmospheres as proxi…
