Sinking Silicates I: Characterizing the benchmark system containing the T0 brown dwarf CWISE J210640.16+250729.0 using JWST

Austin Rothermich, Jacqueline K. Faherty, Ben Burningham +16

In this study, we present the full (97.3\% complete) 0.8--12.5 m spectral energy distribution (SED) of an L/T transition object, CWISE J210640.16+250729.0 (CW2106), using the Ja…

Inspecting Cloudy Substellar Atmospheres with JWST MIRI Synthetic Magnitudes from Spitzer Mid-infrared Spectra

Jolie LHeureux, Genaro Suárez, Johanna M. Vos +4

We examine the positions of substellar objects in mid-infrared color-magnitude and color-color diagrams to distinguish between cloudy and cloud-free atmospheres. Using Spitzer mid-…

The JWST weather report from the nearest brown dwarfs III: Heterogeneous clouds and Thermochemical instabilities as possible drivers of WISE 1049AB's spectroscopic variability

Natalia Oliveros-Gomez, Elena Manjavacas, Theodora Karalidi +17

We present a new analysis of the spectroscopic variability of WISE~J104915.57531906.1AB (WISE~1049AB, L7.5+T0.5), observed using the NIRSpec instrument onboard the James Webb Sp…

Diversity of Cold Worlds: Predicted Near- to Mid-infrared Spectral Signatures of a Cold Brown Dwarf with Potential Auroral Heating

Genaro Suárez, Jacqueline K. Faherty, Ben Burningham +12

Recent JWST/NIRSpec observations have revealed strong methane emission at 3.326 microns in the 482 K brown dwarf CWISEP J193518.59154620.3 (W1935). Atmospheric modeling…

The JWST weather report from the nearest brown dwarfs II: Consistent variability mechanisms over 7 months revealed by 1-14 m NIRSpec + MIRI monitoring of WISE 1049AB

Xueqing Chen, Beth A. Biller, Xianyu Tan +22

We present a new epoch of JWST spectroscopic variability monitoring of the benchmark binary brown dwarf WISE 1049AB, the closest, brightest brown dwarfs known. Our 8-hour MIRI low…
