Title: AXAF OBSERVATIONS OF A BRIGHT BLACK HOLE X-RAY BINARY IN OUTBURST
Observer: Lewin
Subject Category: BH and NS Binaries
Seq: 400051 ObsId: 00684
Long-term Plan bin: 13-May-2000
ABSTRACT
We propose to study the X-ray spectra of black-hole (candidate) X-ray binaries (BHXBs) in outburst. We will follow the outburst throughout its evolution across all wavelength bands, and will select certain periods for X-ray spectral analysis with AXAF. High-resolution X-ray spectra of the BHXBs will likely exhibit emission lines and absorption edges characteristic of the accretion disk geometry, temperatures, and abundances. We expect that they will show the general-relativistic effects of the extreme gravitational environment near the black hole. When possible, we will make (near) simultaneous radio, IR, optical, X-ray timing (RXTE), and gamma-ray (CGRO-BATSE) observations. Our team has extensive expertise in all aspects of the proposed research.
