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…

Modelling the 3D atmospheric structure of the cold Jupiter WD1856+534b orbiting a white dwarf
Pascal A. Noti, Elspeth K. H. Lee, Daniel Kitzmann +5
WD-1856b+534b (WD-1856b) is to date the only detected cold Jupiter outside of our Solar System. This cold Jupiter can provide useful information about the cold giants in our Solar…

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…
