INTEGRAL observation of hard X-ray variability of the TeV binary LS5039 / RX J1826.2-1450
A. D. Hoffmann, D. Klochkov, A. Santangelo +4
LS 5039/RX J1826.2-1450 is one of the few High Mass X-ray binary systems from which radio and high energy TeV emission has been observed. Moreover, variability of the TeV emission…
High variability in Vela X-1: giant flares and off states
Ingo Kreykenbohm, Joern Wilms, Peter Kretschmar +6
We investigate the spectral and temporal behavior of the high mass X-ray binary Vela X-1 during a phase of high activity, with special focus on the observed giant flares and off st…
Giant outburst of EXO 2030+375: pulse-phase resolved analysis of INTEGRAL data
D. Klochkov, A. Santangelo, R. Staubert +1
In June-September 2006 the Be/X-ray binary EXO 2030+375 experienced the second giant outburst since its discovery. The source was shown to have a complicated pulse-averaged X-ray s…
INTEGRAL observations of the variability of OAO 1657-415
J. Barnstedt, R. Staubert, A. Santangelo +7
The Galactic Plane Scan (GPS) was one of the core observation programmes of the INTEGRAL satellite. The highly variable accreting pulsar OAO 1657-415 was frequently observed within…
The pre-outburst flare of the A 0535+26 August/September 2005 outburst
I. Caballero, A. Santangelo, P. Kretschmar +11
We study the spectral and temporal behavior of the High Mass X-ray Binary A 0535+26 during a `pre-outburst flare' which took place ~5 d before the peak of a normal (type I) outburs…
INTEGRAL observation of the accreting pulsar 1E1145.1-6141
Carlo Ferrigno, Alberto Segreto, Teresa Mineo +2
We analyze 1050 ks of INTEGRAL data of the high mass X-ray binary pulsar 1E 1145.1-6141 to study its properties over a long time baseline, from June 2003 to June 2004, with wide sp…
