The X-ray fast-time variability of Sco X-2 (GX 349+2) with RXTE
Sco X-2 (GX 349+2) is a low-mass X-ray binary and Z source. We have analysed ∼156 ks of Rossi X-ray Timing Explorer data, obtained in 1998 January, on this source. We investigated the fast-time variability as a function of position on the Z track. During these observations, Sco X-2 traced out the most extensive Z track ever reported from this object, making this the most comprehensive study thu...
متن کاملOn the X - ray fast - time variability of Sco X - 2 ( GX 349 + 2 ) Paul
We have analysed archived Ginga data on the Z source Sco X-2 (GX 349+2). We present the first detailed investigation of its X-ray fast-time variability, as a function of position in the Z track. During the two-day observation over the period 5–7 March 1989, the source was in the so-called flaring branch, and the lower part of the socalled normal branch. We found broad peaked noise with a centro...
متن کاملCorrelated X–ray timing and spectral behavior of GX 349+2: RXTE PCA data
We present a detailed and systematic investigation of correlated spectral and timing properties of the Z source GX 349+2, using a huge amount (∼ 40 ks) of good quality data from September 29, 1998 to October 13, 1998, obtained with the Proportional-Counter-Array on-board RXTE satellite. We, for the first time, give a detailed comparison between the normal-branch-properties and the flaring-branc...
متن کاملGx 9+9: Variability of the X-ray Orbital Modulation
Results of observations of the Galactic bulge X-ray source GX 9+9 by the All-Sky Monitor (ASM) and Proportional Counter Array (PCA) onboard the Rossi X-ray Timing Explorer are presented. The ASM results show that the 4.19 hour X-ray periodicity first reported by Hertz and Wood in 1987 was weak or not detected for most of the mission prior to late 2004, but then became strong and remained strong...
