Discovery of a Transient Absorption Edge in the X-ray Spectrum of GRB 990705
L. Amati, F. Frontera, M. Vietri +18
We report the discovery of a transient equivalent hydrogen column density with an absorption edge at ~3.8 kiloelectron volts in the spectrum of the prompt x-ray emission of gamma-r…
Discovery of a redshifted Iron K-line in the X-ray afterglow of GRB 000214
L. A. Antonelli, L. Piro, M. Vietri +13
We report the detection (3 sigma significance level) of a strong iron emission line in the X-ray spectrum of the afterglow of GRB 000214 (``Valentine's Day Burst'') observed by Bep…
Canonical Timing and Spectral Behavior of LMC X-3 in the Low/Hard State
Patricia T. Boyd, Alan P. Smale, Jeroen Homan +3
We present results from three observations with the Rossi X-ray Timing Explorer (RXTE) of LMC X-3, obtained while the source was in an extended 'low/hard' state. The data reveal a…
An Atlas of Burst Oscillations and Spectral Properties in 4U 1728-34
Steve van Straaten, Michiel van der Klis, Erik Kuulkers +1
We study correlations between the burst properties and the position in the color-color diagram of the low mass X-ray binary 4U 1728-34 using 21 bursts found in two data sets obtain…
Wide band observations of the new X-ray burster SAX J1747.0-2853 during the March 1998 outburst
L. Natalucci, A. Bazzano, M. Cocchi +4
We report on our discovery and follow-up observations of the X-ray source SAX J1747.0-2853 detected in outburst on 1998, March 10 with the BeppoSAX Wide Field Cameras in the energy…
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…
X-ray Spectral Diagnostics of Gamma-Ray Burst Environments
Frits Paerels, Erik Kuulkers, John Heise +1
Recently, the detection of discrete features in the X-ray afterglow spectra of GRB970508 and GRB970828 was reported. The most natural interpretation of these features is that they…
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…
The power spectral properties of the Z-source GX 340+0
Peter G. Jonker, Michiel van der Klis, Rudy Wijnands +6
We present an analysis of ~390 ksec of data of the Z source GX 340+0 taken during 24 observations with the Rossi X-ray Timing Explorer satellite. We report the discovery of a new b…
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…
