2006 Supplement 1: WORKSHOP ON MULTIFREQUENCY BEHAVIOUR OF HIGH ENERGY COSMIC SOURCES: Frascati, 2005 / Iaria
Study of Two BeppoSAX Observations of GX 340+0
Abstract
We present the results of two BeppoSAX broad band (0.1–200 keV) observations of the Z-source GX 340+0 comparing our results to those of a previous observation of the source. From the color–color diagram we selected three zones and extracted the source energy spectrum from each zone. We find that the model, composed by a blackbody plus a Comptonized component, absorbed by an equivalent hydrogen column of ~6×1022 cm−2, well fits the spectra in the energy range below 30 keV. At higher energies a power law component with photon index of 2.5 is observed. The associated flux decreases going from the horizontal branch to the flaring branch of the Z-track.
