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…

GRB 990510: linearly polarized radiation from a fireball
S. Covino, D. Lazzati, G. Ghisellini +12
Models for gamma-ray burst afterglows envisage an hyper-relativistic fireball that is decelerated in the ambient medium around the explosion site. This interaction produces a shock…

BeppoSAX monitoring of the ``anomalous'' X-ray pulsar 4U 0142+61
G. L. Israel, T. Oosterbroek, L. Angelini +7
The 8.7s X-ray pulsar 4U 0142+61 was monitored by BeppoSAX between January 1997 and February 1998. This source belongs to the rapidly growing class of "anomalous" X-ray pulsars (AX…
