We report an attempt to construct unified cloudy models of M, L, and T dwarfs. For this purpose, we first discuss opacities as well as thermochemical properties of the cool and dense matter. Below about 2000 K, refractory material condenses, and dust will play a major role as a source of opacity. Then a major problem in modeling the photospheres of very cool dwarfs is how to treat dust and, especially, how dust could be sustained in the static photosphere for a long time. Under the high density… Expand
Dust in the Photospheric Environment II. Effect on the Near Infrared Spectra of L and T Dwarfs
We report an attempt to interpret the spectra of L and T dwarfs with the use of the unified cloudy model (UCM). For this purpose, we extend the grid of the UCMs to cases of log g = 4.5 and 5.5. TheExpand
Dust in the Photospheric Environment. III. A Fundamental Element in the Characterization of Ultracool Dwarfs
Recent photometry of L and T dwarfs revealed that the infrared colors show a large variation at a given effective temperature, and within the framework of our unified cloudy model (UCM), this resultExpand
Dust in brown dwarfs - III. Formation and structure of quasi-static cloud layers
In this paper, first solutions of the dust moment equations developed in (Woitke & Helling 2003) for the description of dust formation and precipitation in brown dwarf and giant gas planetExpand
The role of convection, overshoot, and gravity waves for the transport of dust in M dwarf and brown dwarf atmospheres
Observationally, spectra of brown dwarfs indicate the presence of dust in their atmospheres while theoretically it is not clear what prevents the dust from settling and disappearing from the regionsExpand
Unified Cloudy Models of L and T Dwarfs - Physical Basis of the Spectral Classification in the Substellar Regime
Based on a simple thermodynamical argument, we proposed a unified cloudy model (UCM) with a warm dust cloud deep in the photosphere. We showed, for the first time, that a single grid of modelExpand
Transition from L to T Dwarfs on the Color-Magnitude Diagram
The color-magnitude (CM) diagram of cool dwarfs and brown dwarfs based on the recent astrometry data is compared with the CM diagram transformed from the theoretical evolutionary tracks via theExpand
Dust in brown dwarfs and extra-solar planets
The precipitation of cloud particles in brown dwarf and exoplanet atmospheres establishes an ongoing downward flux of condensable elements. To understand the efficiency of cloud formation, it isExpand
Dust in brown dwarfs and extra-solar planets - I. Chemical composition and spectral appearance of quasi-static cloud layers
Aims. Brown dwarfs are covered by dust cloud layers which cause inhomogeneous surface features and move below the observable τ = 1 level during the object’s evolution. The cloud layers have a strongExpand
A comparison of chemistry and dust cloud formation in ultracool dwarf model atmospheres
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 these 'dust' cloudsExpand
We present an analysis of the 0.95-14.5 ?m spectral energy distributions of nine field ultracool dwarfs with spectral types ranging from L1 to T4.5. Effective temperatures, gravities, and condensateExpand


Unified Model Photospheres for Ultracool Dwarfs of Types L and T
The presence of the two distinct groups of ultracool dwarfs (UCDs), ‘L’ and ‘T’ types, is now well established: L dwarfs are thought to be dusty while T dwarfs show strong bands of methane (CH4) butExpand
Warm Dust in the Cool Brown Dwarf Gliese 229B and Spectroscopic Diagnosis of Dusty Photospheres
Dust should be formed in the photosphere of cool brown dwarfs, but it is not clear in what form the dust exists. We propose a model in which a rather warm dust layer exists deep in the photosphere.Expand
