X-ray spectral variability of low-mass X-ray binaries
The author reports on a study of the x-ray spectral variability of 37 low-mass x-ray binaries (LMXRB). The sample studied consists of all LMXRB which were...
X-ray spectroscopy of faint X-ray background sources.
We present results on the X-ray spectral analysis of the XMM-Newton deep surveys on the Lockman Hole and Chandra Deep Field South fields. Using the results of...
The neutron star X-ray transient 4U 1608-52 is often in a state of outburst (e.g. ATel #1113); the Swift/BAT light curve shows three clear outburst peaks so far...
The ROSAT X-ray observations were carried out at three different epochs between 1992 and 1996. Two PSPC (called "A" and "B") and one HRI ("H") observations were...
On Nov 19, 2001, The Chandra X-ray Observatory surveyed M31 with 5 overlapping very short (1ks) HRC exposures and a single short (5ks) ACIS-S exposure...
A bright X-ray transient was detected by Chandra on 2002 June 2 with a series of 5 HRC-I snapshots. The new source CXOU J004154.6+405648 (R.A.=00h41m54s.64, Dec...
Chandra observations on Jan 16, 2002 surveyed M31 with a series of 5 short (1ks) HRC images. Preliminary analysis yields the following info on new transients...
