We report on RXTE observations of the microquasar XTE J1550-564 during a ~70 day outburst in 2000 April-June. We present the PCA+HEXTE 3-200 keV energy spectra of the source and study their evolution over the outburst. The spectra indicate that the source transited from an initial low hard state (LS) to an intermediate state (IS) characterized by a ~1 crab maximum in the 1.5-12 keV band and then went back to the LS. The source shows a hysteresis effect such that the second transition occurs at… 
XTE J1550–564: INTEGRAL Observations of a Failed Outburst
The well-known black hole X-ray binary transient XTE J1550-564 underwent an outburst during the spring of 2003, which was substantially underluminous in comparison to previous periods of peak
An Improved Dynamical Model for the Microquasar XTE J1550–564
We present an improved dynamical model of the X-ray binary and microquasar XTE J1550?564 based on new moderate-resolution optical spectroscopy and near-infrared photometry obtained with the 6.5?m
An X-Ray Timing Study of XTE J1550–564: Evolution of the Low-Frequency Quasi-periodic Oscillations for the Complete 2000 Outburst
We report on RXTE observations of the microquasar XTE J1550-564 during a ~70 day outburst in 2000 April-June. We focus here on the temporal properties of the source and study the behavior of
The discovery outburst of the X-ray transient IGR J17497-2821 observed with RXTE and ATCA
We report the results of a series of RXTE and ATCA observations of the recently discovered X-ray transient IGR J17497-2821. Our 3-200 keV PCA+HEXTE spectral analysis shows very little variations over
Modeling the Hard States of XTE J1550–564 during Its 2000 Outburst
We study the hard states of the black hole binary XTE J1550-564 during its 2000 outburst. In order to explain those states at their highest luminosities, L similar to 10% of the Eddington luminosity,
IS THE CORONA THE SOURCE OF THE EJECTED MATERIAL IN MICROQUASARS
Microquasar outbursts are characterized by spectral state transitions. The transitions between states characterized by a hard spectrum and those characterized by a soft spectrum are of particular
