Context. Miras and long-period variables (LPVs) are radially pulsating, highly evolved stars on the Asymptotic Giant Branch. Because of peculiar conditions of this objects, their cool, extended atmospheres are ideal sites for the formation of dust pa

We investigate the effects of stochastic density fluctuations on the dust temperatures and the resulting infrared (IR) emission spectra of interstellar clouds as an extension of preceding investigations by Hegmann & Kegel. We consider absorption and

We present observational line data for five Bok Globules. Observations were made in the J = 2 → 1 and J = 3 → 2 rotational transitions of CO, 13 CO and C 18 O at the Heinrich-Hertz-Telescope in Arizona. Using the stochastic radiative transfer mod

We study the effects of stochastic density fluctuations on the transport of far-ultraviolet radiation in interstellar clouds. The physical processes considered are absorption and anisotropic scattering by dust grains. We consider clouds that are, on

We study the formation of CO molecules at the edge of dense molecular clouds. As shown by van Dishoeck & Black 1988 the CO photodissociation process is dominated by line rather than continuous absorption. Hence, a turbulent velocity field, modifying

Long-period variables (LPVs) and Miras are highly evolved stars at the upper region of the asymptotic giant branch. They exhibit a pronounced variability of their luminosity with a more or less well defined period and suffer large mass loss in the fo
