I will present the results of several studies aimed at understanding the evolution of the PAH and dust properties, as a function of both the environmental conditions and the metal enrichment of the system. I will first discuss the detailed variations of the mid-IR aromatic features through Galactic regions and nearby galaxies, and how these features can be related to the physical conditions. I will show how models of photodissociation regions can be used to investigate this subject. Then, I will discuss the long term evolution of dust in galaxies, comparing the grain production by various stellar progenitors to their destruction by SN blast waves and in HII regions.
The topics of the CARMA seminar include the solar system, star formation, the interstellar medium, galactic structure and galaxies. All are welcome to attend. Seminars will be limited to 1 hour including questions.
