X-Ray Variability of Neutron Stars versus Black Holes.

In the recent years, thanks to the RXTE satellite, our knowledge of the properties of aperiodic time variability of compact binaries increased enormously. Here I briefly summarize the current status both for neutron star and black hole systems and concentrate on the similarities between these two classes. I show that there is increasing evidence that the main processes that produce the variability are the same for black holes and neutron stars. [ABSTRACT FROM AUTHOR]
