The periodic bursters XB1323-619 and GS1826-24: longterm evolution of the nuclear burning regime and comparison with theory
M. Balucinska-Church, D. Reed, M. J. Church
The majority of X-ray burst sources do not display a burst rate that increases with luminosity as expected, but this is seen in the two clocked bursters XB1323-619 and GS1826-24. W…
An explanation of the Z-track sources
M. J. Church, G. S. Halai, M. Balucinska-Church
We present an explanation of the Z-track phenomenon based on spectral fitting of RXTE observations of GX340+0 using the emission model previously shown to describe the dipping LMXB…
Discovery of absorption features of the ADC and systematic acceleration of the X-ray burst rate in XB 1323-619
M. J. Church, D. Reed, T. Dotani +2
We present results from analysis of the observation of the dipping, quasi-periodic bursting LMXB XB 1323-619 made with XMM-Newton in Jan., 2003. A number of absorption lines were d…
Discovery of hard X-ray features around hotspots of Cygnus A
M. Balucinska-Church, M. Ostrowski, L. Stawarz +1
We present results of analysis of a Chandra observation of Cygnus A in which the X-ray hotspots at the ends of the jets are mapped in detail. A hardness map reveals previously unkn…
The orbital period of the dipping, bursting, globular cluster X-ray source XB 1746-371 from Rossi X-ray Timing Explorer observations
M. Balucinska-Church, M. J. Church, A. P. Smale
We present results from two long observations of XB 1746-371 by the Rossi X-ray Timing Explorer (RXTE) in 2002 January and May, lasting 4 and 5 days respectively. Dips are observed…
