Characterizing the Low-Frequency QPO behavior of the X-ray Nova XTE J1550-564
Gregory J. Sobczak, Ronald A. Remillard, Michael P. Muno +1
For all 209 RXTE observations of the 7-Crab X-ray nova XTE J1550-564, we analyzed the X-ray power spectra, phase lags, and coherence functions. These observations cover the entire…

X-ray Nova XTE J1550-564: Discovery of a QPO Near 185 Hz
R. A. Remillard, J. E. McClintock, G. J. Sobczak +4
We have investigated the X-ray timing properties of XTE J1550-564 during 60 RXTE PCA observations made between 1998 September 18 and November 28. We detect quasi-periodic oscillati…
