- Title
DIALECTICS OF THE PAH ABUNDANCE TREND WITH METALLICITY.
- Authors
Galliano, F.
- Abstract
This paper reviews the various processes that have been proposed to explain the observed trend of PAH strength with metallicity. It summarizes a study showing that, although PAH destruction by hard radiation is important in low-metallicity environments, it is not sufficient to explain their paucity. In these systems, the deficiency of their formation mechanism, related to stellar evolution, has to be invoked.
