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…
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…
BeppoSAX spectroscopy of the globular cluster X-ray source X1746-371 (NGC6441)
A. N. Parmar, T. Oosterbroek, M. Guainazzi +3
During a BeppoSAX observation of the X-ray source X1746-371 located in the globular cluster NGC6441 a type I X-ray burst, parts of 4 intensity dips, and energy dependent flaring we…
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…
BeppoSAX observations of Mkn 3: Piercing through the torus of a Seyfert 2 galaxy
M. Cappi, L. Bassani, A. Comastri +15
A new BeppoSAX broad-band (0.6-150 keV) spectrum of the Seyfert 2 galaxy Mkn 3 is presented. The spectrum provides a direct measurement of a large, neutral column of gas with Nh~10…
