For the calculation of complex neutral/ionized gas phase chemical equilibria, we present a semi-analytical versatile and efficient computer program, called FastChem. The applied method is based on the solution of a system of coupled nonlinear (and li

We have theoretically investigated a number of cyclic molecules of four kinds: XC2H2, XC2H4, XC2, and HXC2, where X can be C, N, O, Na, Mg, Al, Si, P, S, and Ca, respectively, which might be present in interstellar and/or circumstellar space, and cal

Context. Dust formation, i.e. the condensation of solid particles from a gas phase, occurs in astrophysical environments that are sufficiently cool and offer a sufficiently high density of condensable species. Since many astrophysical systems in whic

Physics and Chemistry of Circumstellar Dust Shells

Autor: Hans-Peter Gail, Erwin Sedlmayr

Circumstellar dust, the astronomical dust that forms around a star, provides today's researchers with important clues for understanding how the Universe has evolved. This volume examines the structure, dynamics and observable consequences of the dust
