The η Carinae spectrum of SS 7311 (=Ve 2-27).

LANDABERRY S.J.C., PEREIRA C.B. and DE ARAUJO F.X.

Abstract (from CDS):

We report new spectroscopic observations of the peculiar emission-line star SS 7311, between 3200Å and 7200Å. A line list is provided with their suggested identifications. From the measurements of several forbidden and permitted emission lines of single ionized iron, we derived the color excess and the excitation temperature. We also discuss the nature of SS 7311 based on data obtained. The spectrum closely resembles not only η 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 AeB[e]-star.
