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…
Disequilibrium Chemistry, Diabatic Thermal Structure, and Clouds in the Atmosphere of COCONUTS-2b
Zhoujian Zhang, Sagnick Mukherjee, Michael C. Liu +12
Located 10.888 pc from Earth, COCONUTS-2b is a planetary-mass companion to a young (150-800 Myr) M3 star, with a wide orbital separation (6471 au) and a low companion-to-host mass…
The Thermal Emission Spectrum of the Nearby Rocky Exoplanet LTT 1445A b from JWST MIRI/LRS
Patcharapol Wachiraphan, Zachory K. Berta-Thompson, Hannah Diamond-Lowe +7
The nearby transiting rocky exoplanet LTT 1445A b presents an ideal target for studying atmospheric retention in terrestrial planets orbiting M dwarfs. It is cooler than many rocky…
Cold day-side winds shape large leading streams in evaporating exoplanet atmospheres
F. Nail, M. MacLeod, A. Oklopčić +3
Recent observations of planetary atmospheres in HAT-P-32 b and HAT-P-67 b reveal extensive outflows reaching up to hundreds of planetary radii. The helium 1083 nm light curves for…
Global weather map reveals persistent top-of-atmosphere features on the nearest brown dwarfs
Xueqing Chen, Beth A. Biller, Johanna M. Vos +10
Brown dwarfs and planetary-mass companions display rotationally modulated photometric variability, especially those near the L/T transition. This variability is commonly attributed…
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…
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…
