CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe show preliminary results of a comparative spectral and timing analysis of the Galactic Black Hole XTE J1650-500, using data from BeppoSAX. A clear relation is present between the evolution of energy spectra and power spectra. The central frequency of a given QPO is increasing with the softening of the energy spectra. This is consistent with the following picture: the spectral evolution from Hard to Soft is occurring together with a decreasing of the dimension of the Comptonizing corona. This also implies that the effect of bulk inflow vs thermal Comptonization is increasing its importance during the softening of the source.

| Abstract: | We show preliminary results of a comparative spectral and timing analysis of the Galactic Black Hole XTE J1650-500, using data from BeppoSAX. A clear relation is present between the evolution of energy spectra and power spectra. The central frequency of a given QPO is increasing with the softening of the energy spectra. This is consistent with the following picture: the spectral evolution from Hard to Soft is occurring together with a decreasing of the dimension of the Comptonizing corona. This also implies that the effect of bulk inflow vs thermal Comptonization is increasing its importance during the softening of the source. | |
