Timing Noise in SGR 1806-20
Peter M. Woods, Chryssa Kouveliotou, Mark H. Finger +9
We have phase connected a sequence of RXTE PCA observations of SGR 1806-20 covering 178 days. We find a simple secular spin-down model does not adequately fit the data. The period…
The Timing Evolution of 4U 1630-47 During its 1998 Outburst
S. W. Dieters, T. Belloni, E. Kuulkers +8
We report on the evolution of the timing of 4U1630-47 during its 1998 outburst using data obtained with the Rossi X-ray Timing Explorer (RXTE). The count rate and position in hardn…
Discovery of a New Soft Gamma Repeater, SGR 1627-41
Peter M. Woods, Chryssa Kouveliotou, Jan van Paradijs +6
We report the discovery of a new soft gamma repeater (SGR), SGR 1627-41, and present BATSE observations of the burst emission and BeppoSAX NFI observations of the probable persiste…
RXTE Observations of the Anomalous Pulsar 4U 0142+61
Colleen A. Wilson, Stefan Dieters, Mark H. Finger +2
We observed the anomalous X-ray pulsar 4U 0142+61 using the Proportional Counter Array (PCA) aboard the Rossi X-ray Timing Explorer (RXTE) in March 1996. The pulse frequency was me…
HEXTE Observations of SGR 1806-20 During Outburst
D. Marsden, R. E. Rothschild, C. Kouveliotou +2
We discuss observations of the soft gamma repeater SGR 1806-20 during the RXTE Target of Opportunity observations made in November 1996. During the ~50 ksec RXTE observation, HEXTE…
