Studies of Hard X-ray Tails in Z sources with RXTE/HEXTE
F. D'Amico, W. A. Heindl, R. E. Rothschild +1
We report RXTE results of spectral analyses of three (Sco X-1, GX 349+2, and Cyg X-2) out of the 6 known Z sources, with emphasis in the hard X-ray emission. No hard X-ray tails we…

HEXTE Detections of Hard X-Ray Tails in Sco X-1
F. D'Amico, W. A. Heindl, R. E. Rothschild +1
We report the detection of a non-thermal hard X-ray component from Sco X-1 based upon the analysis of 20-220 keV spectra obtained with the HEXTE experiment on-board the RXTE satell…
