Circumstellar Dust Condensation Scenarios
Astrophysics and Space Science, 1997Circumstellar 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

Properties of circumstellar dust in symbiotic Miras
2006Symbiotic binaries with a cool Mira component are characterized by the presence of substantial dust and by the appearance of near-IR obscuration intervals. To understand such symbiotic Miras, their evolution, mutual interactions between the components and circumstellar matter, the influence of stellar winds and mass transfer mechanism, it is essential ...

Evidence for the circumstellar formation of dust
Astronomische Nachrichten, 1971AbstractFrom an examination of the catalogue of early‐type stars by Neckel it follows that O stars generally have a mean circumstellar extinction AV = 0.89 ± 0.55 mag. On the basis of this result the consequences of the hypothesis are considered that all interstellar dust was formed in circumstellar regions in the process of star formation.

Dust production in circumstellar space
Astronomische Nachrichten, 1971AbstractObservational indications which point out that the formation of dust particles in the circumstellar space usually accompanies the formation of most stars are discussed. An analytic treatment of circumstellar crushing processes leading to dust grains is presented.

Circumstellar Dust in Massive Stars
2010We review observed properties of dust surrounding both hot and cool massive stars. The chemical composition of the dust provides information on the chemical and physical conditions at the time of dust formation, and the geometry of the dust envelope can be used to study the physics of the wind and the interaction between previous and current mass loss.
