Circumstellar dust condensation scenarios

Circumstellar dust condensation is a ubiquitously observed phenomenon. Its adequate physical description and quantitative theoretical modelling usually require i) the treatment of the microscopic grain formation processes, and ii) the simultaneous determination of the local physical and chemical conditions by calculating a consistent model structure of the system under consideration. In this sense, the actual dust formation process and the individual nature of the dust forming object are intimately coupled. It is the aim of this contribution to visualize this interplay in a rather schematic and abstract way by focusing on the essential interaction of evolution trajectories and dust formation windows for stationary, pulsational, and episodic situations, as well.
