The need for small-scale turbulence in atmospheres of substellar objects
Christiane Helling
Brown dwarfs and giant gas planets are substellar objects whose spectral appearance is determined by the chemical composition of the gas and the solids/liquids in the atmosphere. A…
Rain and clouds in brown dwarf atmospheres: A coupled problem from small to large
Ch. Helling, P. Woitke
The large scale structure of a brown dwarf atmosphere is determined by an interplay of convection, radiation, dust formation, and gravitational settling, which possibly provides an…
The multi-scale dust formation in substellar atmospheres
Christiane Helling, Rupert Klein, Erwin Sedlmayr
Substellar atmospheres are observed to be irregularly variable for which the formation of dust clouds is the most promising candidate explanation. The atmospheric gas is convective…
Dust in Brown Dwarfs IV. Dust formation and driven turbulence on mesoscopic scales
Ch. Helling, R. Klein, P. Woitke +2
Dust formation in brown dwarf atmospheres is studied by utilising a model for driven turbulence in the mesoscopic scale regime. We apply a pseudo-spectral method where waves are cr…
