Abstract:

A general multi-component method for the description of dust grain processing

D. Krüger, P. Woitke and E. Sedlmayr

Astronomy & Astrophysics Sup., Vol. 113, 593-602 (1995)

Gzipped PostScript version (241 KB)

Abstract:

We derive a special differential form of a balance or conservation equation for the grain size distribution function. This equation describes the evolution of the grain size spectrum in one-dimensional stationary flows also taking into account possible size dependent drift velocities of the grains relative to the

Circumstellar Dust Shells around Long-Period Variables: IV. Brightness profiles and spatial spectra of C-stars

J.M. Winters, A.J. Fleischer, A. Gauger and E. Sedlmayr

Astronomy & Astrophysics, Vol. 302, 483-496 (1995)

Gzipped PostScript version (274 KB)

Abstract:

Theoretical brightness profiles and spatial spectra of dynamical models for circumstellar dust shells of long-period variables are presented.

Two-fluid models for stationary dust driven winds: I. Momentum and energy balance

D. Krüger, A. Gauger, and E. Sedlmayr

Astronomy & Astrophysics, 290, 573-589 (1994)

Gzipped PostScript version (284KB)

Abstract:

Self-consistent two-fluid models of stationary dust driven winds around cool C-stars have been calculated. The dust and the gas component are coupled by the condensation of dust from the gas phase and grain-gas collisions and are described by separate sets of equations.
