Symbiotic Stars
Abstract
Observations of symbiotic stars (SSs) obtained with the IUE satellite since its launch in 1978 are reviewed. The general features of SS spectra are discussed (IR emission from a cool highly evolved star and UV emission from a nebula ionized by a source of 100,000 K or hotter), and the astrophysical interest of SSs is indicated. Particular attention is given to the S-type SSs AG Peg, AR Pav, Z And, HBV 475, AG Dra, and CH Cyg; the D-type SSs R Aqr, V 1016 Cyg, and RR Tel; SSs in other galaxies; the UV continuum, emisssion lines, abundances, electron temperatures, Doppler shifts, and Doppler broadening and line profiles; and theoretical models based on multispectral information. Sample spectra, graphs, and tables listing SS parameter values are provided.
