A study of the spectral evolution during dipping in XB 1323-619 with Rossi-XTE and BeppoSAX
R. Barnard, M. Balucinska-Church, A. P. Smale +1
We report results from analysis of the observations of the dipping low mass X-ray binary XB 1323-619 made with BeppoSAX} and Rossi-XTE. The dust-scattered halo contributes signific…
Understanding the LMXB X2127+119 in M15 I. X-ray eclipses and dips
Zach Ioannou, T. Naylor, A. P. Smale +2
We present X-ray observations of the high-inclination low-mass X-ray binary system X2127+119 (AC211) in the globular cluster M15 (NGC 7078). The observations consist of data acquir…
Neutron star blackbody contraction during flaring in X1624-490
M. Balucinska-Church, R. Barnard, M. J. Church +1
We present results of an investigation of the physical changes taking place in the emission regions of the LMXB X1624-490 during strong flaring in RXTE observations. Based on the d…
A Second Intense Burst with Photospheric Radius Expansion from X2127+119 in M15
Alan P. Smale
In 2000 September we observed a bright X-ray burst from X2127+119 with the Rossi X-ray Timing Explorer. This burst has a multi-peaked profile, a peak luminosity of ~6.5x10^{38} erg…
ASCA Observation of MS 1603.6+2600 (=UW Coronae Borealis): a Dipping Low-Mass X-ray Binary in the Outer Halo?
Koji Mukai, Alan P. Smale, Caroline K. Stahle +2
MS 1603.6+2600 is a high-latitude X-ray binary with a 111 min orbital period, thought to be either an unusual cataclysmic variable or an unusual low-mass X-ray binary. In an ASCA o…
Day-Scale Variability of 3C 279 and Searches for Correlations in Gamma-Ray, X-Ray, and Optical Bands
R. C. Hartman, M. Villata, T. J. Balonek +36
Light curves of 3C 279 are presented in optical (R-band), X-rays (RXTE/PCA), and gamma rays (CGRO/EGRET) for 1999 Jan-Feb and 2000 Jan-Mar. During both of those epochs the gamma-ra…
