A Comparative Study of the UV and X-Ray Line Spectra of Four Binary X-Ray Sources
Abstract
We propose IUE observations of four optically identified galactic X-ray sources: Cyg X-2, AM Her, SS Cyg, U Gem. In the coming year, we are going to observe these sources with HEAO-B. We expect to measure soft X-ray spectra and will be able to detect X-ray emission lines with high resolution. We want to compare the soft X-ray and UV spectra with particular attention to line emission. This will determine ionization states, temperature(s), and abundances. The combination of UV and X-ray data will span a particularly broad range of temperature and will be most valuable in determining the nature of these objects.
