BeppoSAX spectroscopy of the Hercules X-1 short-on state

T. Oosterbroek, A. N. Parmar, D. Dal Fiume +4

We present results of a 5.7 day duration BeppoSAX observation of the short-on state of Her X-1 and a short observation during the decline of the preceding main-on state. The 0.1-10…

The BeppoSAX 1-8 keV cosmic background spectrum

A. Vecchi, S. Molendi, M. Guainazzi +2

The spectrum of the 1.0-8.0 keV cosmic X-ray background (CXB) at galactic latitudes > 25 degrees has been measured using the BeppoSAX LECS and MECS instruments. The spectrum is con…

The broad-band spectrum of OAO1657-415 with BeppoSAX: In search of cyclotron lines

M. Orlandini, D. Dal Fiume, S. Del Sordo +4

We report on a 30 ks observation of the high-mass X-ray binary pulsar OAO1657-415 performed by BeppoSAX on September 1998. The wide band spectrum is well fit by both a cutoff power…

A BeppoSAX study of the pulsating transient X0115+63: the first X-ray spectrum with four cyclotron harmonic features

A. Santangeo, A. Segreto, S. Giarrusso +9

The recurrent hard pulsating X-ray transient §was observed with \B on March 19, when the source was at a 2--10 keV flux level of 310~mCrab. We report on the high energy spect…

BeppoSAX broad-band observations of Gamma Cassiopeiae

A. Owens, T. Oosterbroek, A. N. Parmar +3

We report broad-band X-ray measurements of the Be star Gamma Cassiopeiae by the BeppoSAX X-ray astronomy satellite. The observations took place on 1998 July, 18-23. The 0.1-200 keV…

A BeppoSAX observation of the massive X-ray binary 4U1700-37

A. P. Reynolds, A. Owens, L. Kaper +2

A 0.5-200 keV BeppoSAX spectrum of the non-pulsating high-mass X-ray binary 4U1700-37 is presented. The spectrum is well characterized by the standard accreting pulsar model of an…
