The BeppoSAX view on the galactic high-mass X-ray binary 4U 0114+65
N. Masetti, M. Orlandini, D. Dal Fiume +5
A pointed observation on the galactic high-mass X-ray binary 4U 0114+65 was carried out with BeppoSAX in order to compare the X-ray spectral and timing characteristics observed by…
Hard X-rays from Type II bursts of the Rapid Burster and its transition toward quiescence
N. Masetti, F. Frontera, L. Stella +10
We report on 4 BeppoSAX Target Of Opportunity observations of MXB 1730-335, the Rapid Burster (RB), made during the 1998 February-March outburst. In the first observation, approxim…
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…
X-ray/optical observations of XTE J0421+560/CI Cam in quiescence
M. Orlandini, A. N. Parmar, F. Frontera +8
We report on a BeppoSAX observation of the transient X-ray source XTE J0421+560 during quiescence performed ~150 days after the 1998 April outburst. The source had an unabsorbed 0.…
Broad-band BeppoSAX observation of the low-mass X-ray binary X1822-371
A. N. Parmar, T. Oosterbroek, S. Del Sordo +4
Results of a 1997 September 9-10 BeppoSAX observation of the 5.57 hr low-mass X-ray binary (LMXRB) X1822-371 are presented. The 0.3-40 keV spectrum is unusually complex and cannot…
Discovery of a faint 437 s X-ray pulsar 1SAX J1452.8-5949
T. Oosterbroek, M. Orlandini, A. N. Parmar +6
A new pulsar, 1SAX J1452.8-5949, was discovered during a BeppoSAX galactic plane survey on 1999 July 20 at R.A.=14h 52m 49s, Dec=-59 49' 18'' (J2000) with a 90% confidence uncertai…
