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…

The Gaia Ultracool Dwarf Sample -- IV. GTC/OSIRIS optical spectra of Gaia late-M and L dwarfs

W. J. Cooper, H. R. A. Jones, R. L. Smart +20

As part of our comprehensive, ongoing characterisation of the low-mass end of the main sequence in the Solar neighbourhood, we used the OSIRIS instrument at the 10.4 m Gran Telesco…

Retrieving Young Cloudy L-Dwarfs: A Nearby Planetary-Mass Companion BD+60 1417B and Its Isolated Red Twin W0047

Caprice L. Phillips, Jacqueline K. Faherty, Ben Burningham +11

We present an atmospheric retrieval analysis on a set of young, cloudy, red L-dwarfs -- CWISER J124332.12+600126.2 and WISEP J004701.06+680352.1 -- using the \textit{Brewster} retr…

Probing the Heights and Depths of Y Dwarf Atmospheres: A Retrieval Analysis of the JWST Spectral Energy Distribution of WISE J035934.06540154.6

Harshil Kothari, Michael C. Cushing, Ben Burningham +5

We present an atmospheric retrieval analysis of the Y0 brown dwarf WISE J035934.06540154.6 using the low-resolution 0.96--12 m JWST spectrum presented in \citet{Beiler_2023}…

Methane Emission From a Cool Brown Dwarf

Jacqueline K. Faherty, Ben Burningham, Jonathan Gagné +21

Beyond our solar system, aurorae have been inferred from radio observations of isolated brown dwarfs (e.g. Hallinan et al. 2006; Kao et al. 2023). Within our solar system, giant pl…
