A model-independent analysis of the variability of GRS 1915+105
T. Belloni, M. Klein-Wolt, M. Mendez +2
We analyzed 163 observations of the microquasar GRS 1915+105 made with the Rossi X-ray Timing Explorer (RXTE) in the period 1996-1997. For each observation, we produced light curve…
Inner accretion disk disappearance during a radio flare in GRS 1915+105
M. Feroci, G. Matt, G. Pooley +3
Simultaneous X-ray (BeppoSAX, 0.1-300 keV) and radio (Ryle Telescope, 15 GHz) observations of the superluminal galactic source GRS 1915+105 in high flux state were carried out star…
Broad Band X-ray Spectra of M31 Sources with BeppoSAX
Ginevra Trinchieri, Gian Luca Israel, Lucio Chiappetti +5
We present the first spectral study of the X-ray emitting stellar sources in M31 in the energy band from 0.1 to 10 keV. We find that the globular cluster sources have spectral char…
A state transition of GX 339-4 observed with RXTE
T. Belloni, M. Mendez, M. van der Klis +2
We report the results of observations with the Rossi X-ray Timing Explorer of the black-hole candidate GX 339-4 during the state transition of 1998. We find that both the X-ray spe…
Soft X-ray emission from intermediate-age open clusters: IC 4651
T. Belloni, G. Tagliaferri
We present the results of soft X-ray observations of the intermediate-age open cluster IC 4651 performed with the ROSAT PSPC. We detected 25 sources. Two are identified with a gian…
