A Comparison of Near-Infrared Photometry and Spectra for Y Dwarfs with a New Generation of Cool Cloudy Models
S. K. Leggett, Caroline V. Morley, M. S. Marley +3
We present YJHK photometry, or a subset, for the six Y dwarfs discovered in WISE data by Cushing et al.. The data were obtained using NIRI on the Gemini North telescope. We also pr…
Towards an Understanding of the Atmospheres of Cool White Dwarfs
Piotr M. Kowalski, Didier Saumon, Jay Holberg +1
Cool white dwarfs with Teff < 6000 K are the remnants of the oldest stars that existed in our Galaxy. Their atmospheres, when properly characterized, can provide valuable informati…
Neglected Clouds in T and Y Dwarf Atmospheres
Caroline V. Morley, Jonathan J. Fortney, Mark S. Marley +3
As brown dwarfs cool, a variety of species condense in their atmospheres, forming clouds. Iron and silicate clouds shape the emergent spectra of L dwarfs, but these clouds dissipat…
Masses, Radii, and Cloud Properties of the HR 8799 Planets
Mark S. Marley, Didier Saumon, Michael Cushing +3
The near-infrared colors of the planets directly imaged around the A star HR 8799 are much redder than most field brown dwarfs of the same effective temperature. Previous theoretic…
New H2 collision-induced absorption and NH3 opacity and the spectra of the coolest brown dwarfs
D. Saumon, M. S. Marley, M. Abel +2
We present new cloudy and cloudless model atmospheres for brown dwarfs using recent ab initio calculations of the line list of ammonia (NH3) and of the collision-induced absorption…
The Properties of the 500 K Dwarf UGPS J072227.51-054031.2, and a Study of the Far-Red Flux of Cold Brown Dwarfs
S. K. Leggett, D. Saumon, M. S. Marley +15
We present i and z photometry for 25 T dwarfs and one L dwarf. Combined with published photometry, the data show that the i - z, z - Y and z - J colors of T dwarfs are very red, an…
