Scientific paper

The author reviews the use of infrared (IR) observations to quantify the physical parameters of classical nova outbursts and to assess their contributions to the interstellar medium (ISM). Metal abundances in the ejecta can be deduced from dust emission features and "coronal" emission. The observations described here can provide basic information about the thermonuclear runaway (TNR) that causes the nova explosion, the chemical composition of the white dwarf (WD) upon which the TNR occurs, and the nature of the WD's progenitor star. The author concludes that some bright novae ejected shells that were extremely overabundant in CNO, Ne, Mg, Al and Si. The properties of dust produced by novae are reviewed and compared to those of the small grains released from comet nuclei.
