SCIENTIFIC ABSTRACT

Cataclysmic variables (CV) include classical and recurrent novae, dwarf
novae and symbiotic stars. They are unique laboratories for
investigating several important astrophysical processes, including
mass-transfer, thermonuclear runaway, dust nucleation and processing,
nebular and coronal emission and fine structure line cooling. Most of
these processes are accessible only to the satellite infrared. The aim of
this proposal is to carry out an investigation of examples of each of
the above types of CV, to study (a) the origin, extent and processing
of dust in CVs; (b) the energetics of fine structure line emission;
(c) the long-term evolution of nova renmnants.

OBSERVATION SUMMARY

We will perform a study of the infrared properties of CVs using LWS and
SWS, CAM and PHOT-S, PHOT-C and PHOT-P. The AOTs have been selected to
give a signal-to-noise of at least 10 at the highest wavelength resolution
possible, over the wavelength range available with ISO. PHOT-P observations
will be used to determine the flux distributions of dwarf novae, classical
novae and symbiotic stars. PHOT-S observations of selected classical novae
and symbiotic stars will be used to investigate dust emission and the
photospheres of CVs with giant secondaries. LWS and SWS observations of
selected classical novae and symbiotic stars will investigate nebular,
coronal and fine structure line emission, and in particular will resolve
ambiguities posed by the inconclusive IRAS broad band observations.
Extended emission around classical and recurrent novae with known resolved
shells will be carried out with PHOT-C and CAM to investigate the
distribution and excitation of molecular, dust and nebular emission.
Observation details are in the section "scientific justification".

CONCATENATION

The intrinsic variability of all the objects in this proposal requires
all observations on the same target to be concatenated.
