Radiative Heating and Cooling in Circumstellar Envelopes

Abstract:

This thesis investigates the thermal state of diluted gases being exposed to stellar radiation fields. On the basis of a steady-state non-LTE description, the radiative heating and cooling rates of the gas are determined, considering the typical densities present in circumstellar envelopes.

Two-fluid models for stationary dust driven winds: II. The grain size distribution in consideration of drift

D. Krüger and E. Sedlmayr

Astronomy & Astrophysics, 321, 557-567 (1997)

Gzipped PostScript version (201 KB)

Abstract:

A multicomponent method for the description of the evolution of the grain size distribution in consideration of a size dependent grain drift and growth rate is applied in order to model dust driven winds around cool C-stars.
