Eta Carinae.
Abstract
IUE observations of the UV spectrum of Eta Car are discussed. The UV spectrum is shown to be dominated by P Cygni profiles of lines due to Fe II and other ions. Several spectral features are identified with emission components, absorption components, or both. The terminal velocity of the stellar wind is estimated to be about -715 km/s.
