The Sonora Substellar Atmosphere Models VI. Red Diamondback: Extending Diamondback with SPHINX for Brown Dwarf Early Evolution
C. Evan Davis, Jonathan J. Fortney, Aishwarya Iyer +5
We extend the Sonora Diamondback brown dwarf evolution models to higher effective temperatures to treat the evolution of younger, higher mass objects. Due to an upper temperature l…
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…
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…
The Strength and Variability of the Helium 10830 Å Triplet in Young Stars, with Implications for Exosphere Detection
Daniel M. Krolikowski, Adam L. Kraus, Benjamin M. Tofflemire +3
Young exoplanets trace planetary evolution, particularly the atmospheric mass loss that is most dynamic in youth. However, the high activity level of young stars can mask or mimic…
CFBDSIR 2149-0403: young isolated planetary-mass object or high-metallicity low-mass brown dwarf??
P. Delorme, T. Dupuy, J. Gagné +12
We conducted a multi-wavelength, multi-instrument observational characterisation of the candidate free-floating planet CFBDSIR~J214947.2-040308.9, a late T-dwarf with possible low-…
The Brown-dwarf Atmosphere Monitoring (BAM) Project II: Multi-epoch monitoring of extremely cool brown dwarfs
A. Rajan, J. Patience, P. A. Wilson +6
With the discovery of Y dwarfs by the WISE mission, the population of field brown dwarfs now extends to objects with temperatures comparable to those of Solar System planets. To in…
Seventy six T dwarfs from the UKIDSS LAS: benchmarks, kinematics and an updated space density
Ben Burningham, C. V. Cardoso, L. Smith +34
We report the discovery of 76 new T dwarfs from the UKIDSS Large Area Survey (LAS). Near-infrared broad and narrow-band photometry and spectroscopy are presented for the new object…
