Multi-Epoch Stability in the Rotational Modulation of the Planetary-Mass Companion Ross 458C
Elena Manjavacas, Jared Bull, Paulo Miles-Paez +7
Spectroscopic variability is detected in brown dwarfs across all spectral types, suggesting atmospheric patchiness in brown dwarf atmospheres. We present JWST/NIRSpec time series o…
Asymmetric nightside CO2 features, inefficient heat transport, and precise evolutionary constraints: Spectroscopic phase curves reveal the past and present of a white dwarf-brown dwarf binary
Daphne Broski-Laing, Yifan Zhou, Joshua D. Lothringer +10
We present the first JWST phase curve of a white dwarf-brown dwarf binary, a NIRSpec PRISM observation of ZTFJ0038+2030. Short-period white dwarf-brown dwarf binaries provide uniqu…
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…
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…
Phase-resolved Hubble Space Telescope WFC3 Spectroscopy of Weakly-Irradiated Brown Dwarf GD 1400 and Energy Redistribution-Irradiation Trends in Six WDBD Binaries
Rachael C. Amaro, Dániel Apai, Yifan Zhou +8
Irradiated brown dwarfs offer a unique opportunity to bridge the gap between stellar and planetary atmospheres. We present high-quality /WFC3/G141 phase-resolved spec…
The only inflated brown dwarf in an eclipsing white dwarf-brown dwarf binary: WD1032+011B
Jenni R. French, Sarah L. Casewell, Rachael C. Amaro +9
Due to their short orbital periods and relatively high flux ratios, irradiated brown dwarfs in binaries with white dwarfs offer better opportunities to study irradiated atmospheres…
The JWST Weather Report from the Nearest Brown Dwarfs I: multi-period JWST NIRSpec + MIRI monitoring of the benchmark binary brown dwarf WISE 1049AB
Beth A. Biller, Johanna M. Vos, Yifan Zhou +22
We report results from 8 hours of JWST/MIRI LRS spectroscopic monitoring directly followed by 7 hours of JWST/NIRSpec prism spectroscopic monitoring of the benchmark binary brown d…
Atmospheric Retrievals of the Phase-resolved Spectra of Irradiated Brown Dwarfs WD-0137B and EPIC-2122B
Joshua D. Lothringer, Yifan Zhou, Daniel Apai +3
We present an atmospheric retrieval analysis of HST/WFC3/G141 spectroscopic phase curve observations of two brown dwarfs, WD-0137B and EPIC-2122B, in ultra-short period orbits arou…
