On the Universal X-ray Luminosity Function of Binary X-ray Sources in Galaxies
The empirically determined universal power-law shape of X-ray luminosity function of high mass X-ray binaries in galaxies is explained by fundamental mass-luminosity and mass-radius relations for massive stars. The unique possibilities offerred by modern X-ray space observatories Chandra and XMM-Newton make it possible to observe point-like X-ray sources in nearby galaxies which allows studies ...
متن کاملHard X-Ray Lightcurves of High Mass X-Ray Binaries
Using the 9 years of continuous data now available from the Burst And Transient Source Experiment (BATSE) aboard CGRO, we have measured orbital periods and produced folded lightcurves for 8 High Mass X-ray Binaries (HMXB). Given the length of the datasets, our determinations are based on many more binary orbits than previous investigations. Thus our source detections have high statistical signi...
متن کاملTiming Analysis of X-ray Lightcurves
This exercise is designed to give a brief introduction to one aspect of timing analysis: Fourier transforms (executed via a Fast Fourier Transform, FFT, of discrete data) and their associated Power Spectral Densities (PSD). Parts of this exercise have been cribbed from Tomaso Belloni’s tutorial that was presented at the European “2 School on Multiwavelength Astronomy” (June 28–July 9, 2010), wh...
متن کاملThe Spectral States of Black Hole X-ray Binary Sources
A framework for the interpretation of the spectral states of black hole X-ray transients based on the diversity of accretion disk models is introduced. Depending on the mass accretion rate, it is proposed that the accretion disk is described by one or a combination of the following structures: optically thick disk, advection-dominated disk, corona-disk, and non-steady state disk. In particular,...
