Dynamics of extended AGB star envelopes
C. Dreyer, M. Hegmann, E. Sedlmayr
The dust formed in extended circumstellar envelopes of long-period variables and Miras has a strong influence on the envelope dynamics. A radiatively driven instability caused by t…

Circumstellar dust shells around long-period variables. X. Dynamics of envelopes around standard luminous, C-rich AGB stars
C. Dreyer, M. Hegmann, E. Sedlmayr
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…

Effects of correlated turbulent velocity fields on the formation of maser lines
R. Boeger, W. H. Kegel, M. Hegmann
The microturbulent approximation of turbulent motions is widely used in radiative transfer calculations. Mainly motivated by its simple computational application it is probably in…
