Chandra Spectroscopic Survey of Black Hole Binaries by
Yuxin Feng X-ray emissions from black hole binaries are believe to be produced in the vicinity around black holes in these systems. The emission line features and absorption line and edge features may be generated from the compact X-ray emission regions, or in the processes of absorption or reflection. The properties of these features are determinate by the temperature, abundance, or density of the plasma surrounding the X-ray source, such as the accretion flow and stellar wind. Identifying and measuring the individual features will provide information about the physical properties and configuration of the material in black hole binary systems. The high spectrum resolution achieved by the High Energy Transmission Gratings (HETG) aboard Chandra X-ray Observatory are essential for determining these spectral features accurately. Recent results on studies of these features as well as the continuum spectra of X-ray emissions from persistent black hole binaries observed with chandra are presented and discussed.
