Study of the Temporal Behavior of 4U 1728-34 as a Function of its Position in the Color-Color Diagram

T. Di Salvo, M. Méndez, M. van der Klis +2

We study the timing properties of the bursting atoll source 4U 1728-34 as a function of its position in the X-ray color-color diagram. In the island part of the color-color diagram…

Phase lag variability associated with the 0.5-10 Hz QPO in GRS 1915+105

P. Reig, T. Belloni, M. van der Klis +3

We have used Rossi X-ray Timing Explorer data to measure the lags between soft (2-5 keV) and hard (5-13 keV) photons and to study the aperiodic variability of the superluminal blac…

Dependence of the Frequency of the Kilohertz Quasi-Periodic Oscillations on X-ray Count Rate and Colors in 4U 1608-52

Mariano Mendez, Michiel van der Klis, Eric C. Ford +2

We present new results based on observations carried out with the Rossi X-ray Timing Explorer during the decay of an outburst of the low-mass X-ray binary (LMXB) and atoll source 4…

Kilohertz Quasi-Periodic Oscillation Peak Separation is not Constant in the Atoll Source 4U 1608-52

Mariano Mendez, Michiel van der Klis, Rudy Wijnands +3

We present new Rossi X-ray Timing Explorer observations of the low-mass X-ray binary 4U 1608-52 during the decay of its 1998 outburst. We detect by a direct FFT method the existenc…

Kilo-hertz QPO in Island State of 4U1608-52 as Observed with RXTE/PCA

W. Yu, S. N. Zhang, B . A. Harmon +8

We report RXTE/PCA observations of 4U 1608-52 on March 15, 18 and 22 immediately after the outburst in early 1996. The persistent count rates ranged from 190 to 450 cps (1-60 keV).…

Energy Spectra and High Frequency Oscillations in 4U 0614+091

Eric C. Ford, Philip Kaaret, Kaiyou Chen +7

We investigate the behavior of the high frequency quasi-periodic oscillations (QPOs) in 4U 0614+091, combining timing and spectral analysis of RXTE observations. The energy spectra…

High-Energy Emission from the PSR B1259-63 System near Periastron

M. Tavani, J. E. Grove, W. Purcell +11

We report the results of a CGRO 3-week observation of the binary system containing the 47 ms pulsar PSR B1259-63 orbiting around a Be star companion in a very eccentric orbit. The…
