TL;DR: In this article, the mean gas and dust opacities relevant to the physical conditions typical of protoplanetary discs were calculated for temperatures between 5 K and 10 000 K and gas densities ranging from 10 −18 gc m −3 to 10 −7 gcm −3.

TL;DR: In this article, an improved description of dust-driven stellar mass-loss for the cool winds of carbon-rich tip-AGB stars was derived, which depends only on the stellar parameters (eective temperature Te, luminosity L and mass M).

TL;DR: In this article, the authors present a self-consistent time-dependent model for the oxygen-rich Mira variable IRC-20197, which includes a consistent treatment of the interactions among hydrodynamics, thermodynamics, radiative transfer, equilibrium chemistry, and heterogeneous dust formation with TiO 2 nuclei.

TL;DR: In this paper, the problem of inorganic dust formation is discussed for the conditions of cool late-type giants and supergiants having an oxygen-rich element composition, and a particular emphasis is put on the formation of the primary condensates, i.e., the first kind of grains forming from the gas phase.

TL;DR: The applied method is based on the solution of a system of coupled non-linear (and linear) algebraic equations, namely the law of mass action and the element conservation equations including charge balance, in many variables.
