Chemical Enrichment of the Interstellar MediumThe aim of these lessons is to show that there is evidence for chemical evolution of the interstellar gas, as proven by the spectroscopic analysis of stars of all ages in the solar neighbourhood, of interstellar molecules and of HII regions both in our Galaxy and in external ones.

Interstellar ChemistryA description is presented of the basic elements of the chemistry of interstellar clouds and the success of models of diffuse, translucent and dense clouds is assessed. The chemical differences between non-dissociative and dissociative shocks are reviewed. A brief discussion is given of the effects of intense ultraviolet radiation fields.

It is the first supernova to be observed in all wavelength bands: radio, infrared, optical, ultraviolet, X-ray and γ-ray, and it is the first supernova from which neutrinos have been detected.
