This site displays X-ray lightcurves and three-dimensional CCI plots using the first 13 years of RXTE data. Only 5 sigma detections are used. Where available we show spectral energy distributions (SEDs) of X-ray binaries from optical to X-ray energy range. Objects can be accessed in RA order or as a function of binary type (BH, NS, HMXB, LMXB). The CCI plots are particularly useful in identifying the different binary types. Superorbital phase and X-ray spectral states can be determined using the RXTE lightcurves of the individual sources. X-ray binaries (XRBs) owe their prominence to one of the most efficient energy release mechanisms known: accretion onto a compact object. Accretion processes are ubiquitous in the Universe and are associated with star formation, interacting main sequence binaries, active galactic nuclei, and quasars. XRBs are the most nearby, easily studied example of the accretion process. They are of additional interest as the endpoints of stellar evolution and serve as laboratories for the study of matter under extreme conditions.

Upper left: Black hole systems with high mass companions in blue, black hole systems
with low mass companions in green, X-ray pulsars in red, and non-pulsing neutron star systems in Cyan.
Upper right: Systems with resolved jets in blue, systems with no jets (pulsars) in red. Lower left: Black hole systems with low-mass companions in green; black hole systems with high-mass companions in blue. Lower right: Persistent black hole systems in blue; transient black hole systems in green. As defined by Mclintock, Narayan, & Steiner (2013). For these particular sources the only change between the two lower plots is that LMC X-3 was switched to transient instead of high-mass. |
