Condensation of grains

These lectures concentrate on the physics and chemistry of the nucleation and growth of grains. The general theory of grain nucleation is explored, and an approximate analytical treatment is developed. The latter is applied to several astrophysical environments, such as novae, supernovae, red giants, planetary nebulae and the proto-solar nebula. The calculation of chemical equilibrium and disequilibrium condensation is explored and applied to the origin of meteorites, especially with regard to the question of isotopic anomalies. The relation of these problems to the origin of the solar system is discussed.
