Sedimentation Efficiency of Condensation Clouds in Substellar Atmospheres
Peter Gao, Mark S. Marley, Andrew S. Ackerman
Condensation clouds in substellar atmospheres have been widely inferred from spectra and photometric variability. Up until now, their horizontally averaged vertical distribution an…
Clouds and Hazes in Exoplanet Atmospheres
Mark S. Marley, Andrew S. Ackerman, Jeffrey N. Cuzzi +1
Clouds and hazes are commonplace in the atmospheres of solar system planets and are likely ubiquitous in the atmospheres of extrasolar planets as well. Clouds affect every aspect o…
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…
A comparison of chemistry and dust cloud formation in ultracool dwarf model atmospheres
Ch. Helling, A. Ackerman, F. Allard +8
The atmospheres of substellar objects contain clouds of oxides, iron, silicates, and other refractory condensates. Water clouds are expected in the coolest objects. The opacity of…
Clouds and Clearings in the Atmospheres of the L and T Dwarfs
M. S. Marley, A. Ackerman, A. J. Burgasser +3
A sophisticated approach to condensate opacity is required to properly model the atmospheres of L and T dwarfs. Here we review different models for the treatment of condensates in…
L-dwarf variability: I-band observations
Christopher R. Gelino, Mark S. Marley, Jon A. Holtzman +2
We report on the results of an I-band photometric variability survey of eighteen L dwarfs. We find that seven exhibit statistically significant variations above the 95.4% confidenc…
