Abstract:

The project described in this contribution aims to study the structure of nova shells and their ionizing sources. This question will be addressed by improved physical and chemical diagnostics derived from spatially resolved spectroscopic observations. New model constraints can be obtained using infrared coronal lines in addition to optical diagnostic lines sampled along the evolution of the nova ejecta.

Instrumentation: The required instrumentation for this project are optical and infrared two-dimensional spectrographs working at low to medium resolution (lambda / (Delta lambda) of about 500-2000). We plan to obtain broad IR coverage (I, J, H, and K). The spectral region from 3.5 mu to 5 mu being desirable but not essential. A spatial resolution of 0.15 to 0.25 arcseconds (FWHM) would be sufficient (see section 3). Absolute flux calibration both in the infrared and in the optical is required.
