The eta Carinae spectrum of SS73 11 (=Ve 2-27)

We report new spectroscopic observations of the peculiar emission-line star SS73 11, between 3200 Angstrom A and 7200 Angstrom. A line list is provide d with their suggested identifications. From the measurements of several fo rbidden and permitted emission lines of single ionized iron, we derived the color excess and the excitation temperature. We also discuss the nature of SS73 11 based on data obtained. The spectrum closely resembles not only et a Car but also some proto-planetary nebulae. On the other hand we concluded that this object is not a B[e]-supergiant, a symbiotic star or a Herbig Ae B[e]-star.
