Abstract
We present the results of the timing and color analysis of more than two
hundred RXTE/PCA observations of the bright black-hole transient GX
339-4 obtained during its 2002/2003 outburst. The color-intensity
evolution of the system, coupled to the properties of its fast time
variability, allow the identification of four separate states. Depending
on the state, strong noise is detected, together with a variety of
quasi-periodic oscillations at frequencies from 0.2 to 8 Hz. We present
a characterization of the timing parameters of these states and compare
them to what has been observed in other systems. These results, together
with those obtained from energy spectra, point towards a common
evolution of black-hole transients through their outbursts.
