Abstract

The authors have obtained FOS spectra of ten locations in the nebulosity surrounding η Car, including two apertures located along the prominent "jet" protruding northeast from the central region. Unlike previous spectra of η Car and its surrounding ejecta, the spectrum in the J1 aperture allows the calculation of a few key chemical abundances free of contamination by reflected light. This is due to the high velocity relative to η Car of the knot of ejecta contained in this aperture. This unique spectrum also yields quantitative insight into the impact of reflected light on chemical abundance determinations in the η Car nebula.
