Water Cloud and Chemical Modulations in the Coldest Brown Dwarf
Brittany E. Miles, James Mang, Caroline V. Morley +24
We present high signal-to-noise, medium resolution (R ~ 1000), time-series JWST/NIRSpec spectra of WISE 0855 (265K), the coldest known brown dwarf. Medium resolution, time-series s…
A Deep Search for Exomoons Around WISE 0855 With JWST
Mikayla J. Wilson, Mary Anne Limbach, Andrew J. Skemer +11
JWST is collecting time-series observations of many free-floating planets (FFPs) to study their weather, but these light curves are the ideal datasets to search for exomoons that t…
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…
A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations
Kento Masuda, Jessica E. Libby-Roberts, John H. Livingston +49
Kepler-51 is a -old Sun-like star hosting three transiting planets with radii - and orbital periods -$130\,\mathrm{day…
High-precision atmospheric characterization of a Y dwarf with JWST NIRSpec G395H spectroscopy: isotopologue, C/O ratio, metallicity, and the abundances of six molecular species
Ben W. P. Lew, Thomas Roellig, Natasha E. Batalha +19
The launch of the James Webb Space Telescope (JWST) marks a pivotal moment for precise atmospheric characterization of Y dwarfs, the coldest brown dwarf spectral type. In this stud…
The impact of spectral line wing cut-off: Recommended standard method with application to MAESTRO opacity database
Ehsan, Gharib-Nezhad, Natasha E. Batalha +8
When computing cross-sections from a line list, the result depends not only on the line strength, but also the line shape, pressure-broadening parameters, and line wing cut-off (i.…
ExoMol line lists -- XXXIX. Ro-vibrational molecular line list for CO
S. N. Yurchenko, Thomas M. Mellor, Richard S. Freedman +1
A new hot line list for the main isotopologue of CO is presented. The line list consists of almost 2.5 billion transitions between 3.5 million rotation-vibration states of CO$_…
Unusual Isotopic Abundances in a Fully-Convective Stellar Binary
I. J. M. Crossfield, J. D. Lothringer, B. Flores +6
Low-mass M dwarfs represent the most common outcome of star formation, but their complex emergent spectra hinder detailed studies of their composition and initial formation. The me…
Chemical consequences of the C/O ratio on hot Jupiters: Examples from WASP-12b,CoRoT-2b, XO-1b, and HD 189733b
J. I. Moses, N. Madhusudhan, C. Visscher +1
Motivated by recent spectroscopic evidence for carbon-rich atmospheres on some transiting exoplanets, we investigate the influence of the C/O ratio on the chemistry, composition, a…
Extrasolar Giant Planet and Brown Dwarf Models
A. Burrows, W. B. Hubbard, J. I. Lunine +3
With the discovery of the companions of 51 Peg, 55 Cnc, Boo, And, 70 Vir, 47 UMa, and Gl229, evolutionary and spectral models of gas giants and/or brown dwarfs with…
