SUMMARY OF SEQUENCE NUMBER 400071

Title: HIGH RESOLUTION X-RAY SPECTROSCOPY OF COMPACT BINARIES

Observer: VRTILEK

Subject Category: BH and NS Binaries

Seq: 400071 ObsId: 00704

Long-term Plan bin: 5-Jun-2000

ABSTRACT

We propose to undertake a survey of Galactic X-ray binaries with the ACIS-S+HETG. Owing to their proximity and brightness, X-ray binaries provide otherwise unobtainable insight into the accretion process. We will: investigate the physical conditions of the emitting gas using emission and recombination line diagnostics to determine temperatures, densities, elemental abundances, and ionization structure; test and improve models of X-ray line emission developed by us over the past decade; and generate an atlas of spectra for use in comparative studies of X-ray binaries. Insights gained from this work will be applicable to irradiated, accreting plasmas which are present in regions of star formation, interacting main-sequence binaries, active galactic nuclei and quasars.
