Spectral and timing analysis of the bursting pulsar GRO J1744-28 with RXTE observations
Long Ji, Andrea Santangelo, Shu Zhang +5
We analyzed RXTE/PCA observations of the bursting pulsar GRO J1744-28 during its two outbursts in 1995-1997. We have found a significant transition, i.e., a sharp change, of both s…
BeppoSAX observations of XTE J1946+274
R. Doroshenko, A. Santangelo, V. Doroshenko +1
We report on the BeppoSAX monitoring of a giant outburst of the transient X-ray pulsar XTE J1946+274 in 1998. The source was detected with a flux of ~ 4 x 10^(-9) erg cm^(-2) s^(-1…
BeppoSAX observations of GRO J1744-28
R. Doroshenko, A. Santangelo, V. Doroshenko +2
We present an analysis of BeppoSAX observations of the unique transient bursting X-ray pulsar GRO J1744-28. The observations took place in March 1997 during the decay phase of the…
XMM-Newton observations of 1A 0535+262 in quiescence
Victor Doroshenko, Andrea Santangelo, Rozaliya Doroshenko +3
Accretion onto magnetized neutron stars is expected to be centrifugally inhibited at low accretion rates. Several sources, however, are known to pulsate in quiescence at luminositi…
The hard X-ray emission of X Per
V. Doroshenko, A. Santangelo, I. Kreykenbohm +1
We present an analysis of the spectral properties of the peculiar X-ray pulsar X Per based on INTEGRAL observations. We show that the source exhibits an unusually hard spectrum and…
