Scientific paper

We propose to obtain low resolution spectra of the shell around Nova Cyg/92 in order to determine element abundances and the nature of the ejecta. FOS spectra will provide line fluxes and give information on the kinematics of the shell, and the FOC will be used with a prism to acquire monochromatic images of the ejecta so surface brightnesses can be determined in the various emission lines. Because of HST's aperture and the FOS UV sensitivity we plan to concentrate on the weaker emission lines that are not normally detected in novae ejecta in order to determine abundances for as many post-neon elements as possible. We also plan to determine the extent to which there are dense condensations in the shell, and their influence in dictating the ionization and providing for dust formation.
