No QPO time lags from Sco X-1 as seen with EXOSAT: a comparison with Cyg X-2
Stefan W. Dieters, Brian A. Vaughan, Erik Kuulkers +2
We have measured the phase-delay and rms amplitude spectra of CygX-2 and ScoX-1. Using EXOSAT data from the normal branch of CygX-2 we confirm earlier (Ginga) results, showing that…
Correlation Between Luminosity and Accretion Torque in 4U 1626-67 and GX 301-2
Brian A. Vaughan, Shunji Kitamoto
We present X-ray light curves and energy spectra for the persistent accreting pulsars 4U 1626-67 and GX 301-2 measured by the All-Sky Monitor (ASM) on Ginga from 1987 March - 1991…
Kilohertz QPO and Atoll Source States in 4U 0614+09
M. Mendez, M. van der Klis, J. van Paradijs +5
We report three RXTE/PCA observations of the low-mass X-ray binary 4U 0614+09. They show strong (~ 30% rms) band-limited noise with a cut-off frequency varying between 0.7 and 15 H…
Discovery of 800 Hz QPO in 4U1608-52
M. Berger, M. van der Klis, J. van Paradijs +11
We present results of RXTE observations of the low-mass X-ray binary and atoll source 4U 160852 made over 9 days during the decline of an X-ray intensity outburst in March 1996.…
