ABSTRACT:The condensation of carbon in cool stellar winds is described by two processes: the formation and the growth of carbon particles.
In contrast to the
assumptions of conventional droplet theory of condensation, these particles were
found to be PAH's.
Their formation and growth is described in terms of
chemical reactions.
The derived temperature of effective condensation fits
the observations.
Structure and abundances of the molecules and
particles at the end of the condensation process are discussed.
