Bowen Fluorescence from Companion Stars in X-ray Binaries
J. Casares, D. Steeghs, R. I. Hynes +3
This paper will review a new technique of detecting companion stars in LMXBs and X-ray transients in outburst using the Bowen fluorescence lines at 4634-4640 Angs. These lines are…
Discovery of 1RXS J171824.2-402934 as an X-ray burster
R. G. Kaptein, J. J. M. in 't Zand, E. Kuulkers +3
We report the first-time detection of a type-I X-ray burst from a position that is consistent with that of 1RXS J171824.2-402934. The detection was made on Sep 23, 1996, with the W…
Turmoil on the accretion disk of GRO J1655-40
E. Kuulkers, J. J. M. in 't Zand, R. Cornelisse +7
During the 1996/1997 outburst of the X-ray transient GRO J1655-40 the Wide Field Cameras onboard BeppoSAX observed the system with nearly continuous coverage during some stages of…
The longest thermonuclear X-ray burst ever observed? (A BeppoSAX Wide Field Camera observation of 4U 1735-44)
R. Cornelisse, J. Heise, E. Kuulkers +2
A long flux enhancement, with an exponential decay time of 86 min, is detected in 4U 1735-44 with the BeppoSAX Wide Field Cameras. We argue that this is a type-I X-ray burst, makin…
BeppoSAX observations of the nearby low-mass X-ray binary and fast transient SAX J1819.3-2525
J. J. M. in 't Zand, E. Kuulkers, A. Bazzano +7
SAX J1819.3-2525 is a nearby X-ray transient which exhibited a fast and large X-ray outburst on Sep. 15, 1999 (Smith et al. 1999). The Wide Field Cameras and the Narrow Field Instr…
The orbital period of the recurrent X-ray transient in Terzan 6
J. J. M. in 't Zand, A. Bazzano, M Cocchi +11
Four or five new outbursts were detected of the bright X-ray transient GRS 1747-312 in the globular cluster Terzan 6 between 1996 and 1999, through monitoring campaigns with the Wi…
