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…

Absorption Line Survey of H3+ toward the Galactic Center Sources III. Extent of the Warm and Diffuse Clouds

M. Goto, T. Usuda, T. R. Geballe +4

We present follow-up observations to those of Geballe & Oka (2010), who found high column densities of H3+ ~100 pc off of the Galactic center (GC) on the lines of sight to 2MASS J1…

SDSS J1534+1615AB: A Novel T Dwarf Binary Found with Keck Laser Guide Star Adaptive Optics and the Potential Role of Binarity in the L/T Transition

Michael C. Liu, S. K. Leggett, David A. Golimowski +5

We have resolved the newly discovered T dwarf SDSS J1534+1615 into a 0.11'' binary using the Keck sodium laser guide star adaptive optics system. With an integrated-light spectral…

An Extremely Large Excess of 18O in the Hydrogen-Deficient Carbon Star, HD 137613

Geoffrey C. Clayton, Falk Herwig, T. R. Geballe +4

We report the discovery of a uniquely large excess of 18O in the hydrogen-deficient carbon (HdC) star, HD 137613, based on a spectrum of the first overtone bands of CO at 2.3-2.4 m…
