Scientific paper

The Planetary Camera and the High Resolution Spectrograph will be used to study the knots of material which have been ejected from Eta Carinae. Two sets of PC images in the light of H-Alpha will be taken at widely separated epochs. Analysis of the images will provide new information about the distribution, morphology and motions of the ejecta. Ultraviolet spectra of two bright knots will be obtained with the HRS. The spectral region 1150-1950A will be observed with configuration G140L, allowing emission line fluxes, profiles, and velocities to be studied. A signal to noise ratio of 25 in the brighter lines is anticipated. Searches for as yet undetected lines of carbon and oxygen will be possible to much fainter limits on the fluxes.
