Scientific paper

We propose to obtain G140L and G230L STIS spectra and nearly contemporaneous ground-based optical spectra of as many as possible of the known symbiotic stars for which no usable ultraviolet data exist. Currently, reliable fundamental parameters are available for only 10 percent of the approximately 150 known or suspected symbiotics. For the components of many individual systems, we will determine physical parameters such as Zanstra temperatures, emission line diagnostic electron temperatures and densities, and limits on red giant wind velocity laws and mass-loss rates. More importantly, we will be able to establish meaningful statistical limits on the nature of hot component sources of ionization and fundamental wind parameters, which are vital steps toward understanding the accretion hydrodynamics and the evolutionary status of symbiotic systems.
