The INTEGRAL LMXRB Monitoring Programme
A. Paizis, T. J. -L. Courvoisier, O. Vilhu +21
Our collaboration is responsible for the study of a sample of 72 low mass X-ray binaries (LMXRB) using the INTEGRAL Core Programme data. In this paper we describe the monitoring pr…
X-Ray Observations of Cygnus X-2
S. Piraino, A. Santangelo, P. Kaaret
We report on a joint BeppoSAX/RossiXTE observation of the Z-type low mass X-ray binary Cyg X-2. The source was in the so-called high overall intensity state and in less than 24 hou…
Detection of a broad iron emission line and sub-millisecond quasiperiodic oscillations from the type I X-ray burster 4U1728-34 in a high state
S. Piraino, A. Santangelo, P. Kaaret
We report results from simultaneous RossiXTE and BeppoSAX observations of the neutron-star x-ray binary and type I X-ray burster 4U1728-34. The source was found in a high luminosit…
BeppoSAX observation of the transient X-ray pulsar GS 1843+00
S. Piraino, A. Santangelo, A. Segreto +8
We present the results from both the timing and spectroscopic analysis of the transient X-ray pulsar GS 1843+00 observed by the BeppoSAX satellite on 1997 April 4, when the source…
BeppoSAX Observations of the galactic source GS1826-238 in a hard X-ray high state
Stefano Del Sordo, Filippo Frontera, Elena Pian +7
The BeppoSAX Narrow Field Instruments observed the galactic source GS1826-238 in October 1997, following a hard X-ray outburst with a peak flux of about 100 mCrab detected by BATSE…
The Vela X-1 pulse-averaged spectrum as observed by BeppoSAX
M. Orlandini, D. Dal Fiume, F. Frontera +7
We report on the 20 ksec observation of Vela X-1 performed by BeppoSAX on 1996 July 14 during its Science Verification Phase. We observed the source in two intensity states, charac…
