The influence of non-isotropic scattering of thermal radiation on spectra of brown dwarfs and hot exoplanets
R. J. de Kok, Ch. Helling, D. M. Stam +2
(abridged) We calculate near-infrared thermal emission spectra using a doubling-adding radiative transfer code, which includes scattering by clouds and haze. Initial temperature pr…

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…

Rosseland and Planck Mean Opacities for Protoplanetary Discs
D. Semenov, Th. Henning, Ch. Helling +2
In this paper, we present mean gas and dust opacities relevant to the physical conditions typical of protoplanetary discs. As the principal absorber for temperatures below ~1,500 K…
