Strongly absorbed quiescent X-ray emission from the X-ray transient XTE J0421+56
L. Boirin, A. N. Parmar, D. Lumb +2
We have observed the soft X-ray transient XTE J0421+56 in quiescence with XMM-Newton. The observed spectrum is highly unusual being dominated by a broad feature at 6.5 keV and can…
Low and High Frequency Quasi-Periodic Oscillations in 4U1915-05
L. Boirin, D. Barret, J. F. Olive +2
The X-ray burster and dipper 4U1915-05 (also known as XB1916-053) was observed 19 times for a total exposure of roughly 140 ks between 1996 February and October with the proportion…
RXTE Broad Band X-ray Spectrum of the Burster 1E1724-3045
J. F. Olive, D. Barret, L. Boirin +1
The X-ray burster 1E1724-3045 located in the globular cluster Terzan 2 is known as one of the persistent (though variable) hard X-ray sources as shown by the SIGMA observations of…
Discovery of High Frequency Quasi-Periodic Oscillations in 4u1915-05
D. Barret, L. Boirin, J. F. Olive +4
The type I X-ray burster and dipper 4U1915-05 (also known as XB1916-053) was monitored by the Rossi X-ray Timing Explorer between February and October, 1996. The source was observe…
