چکیده
We heve investigated the temporal behavior of the x-ray emission from Sco X-1 on 3 March 1969, based upon data obtained over a continuous 122 sec exposure in tha energy range 2 20 keV, where the count was recorded each 322 μsec. We find no evidence for any temporal structure in the data. The ., Q upper limits on the pulsed fraction at any given period are below 1% for periods in the range 3 300 msec. We also establish upper limits for non-periodic variations over times from a fraction of a msec to about 1 minute. Any corttinuot±s x-ray flickering on the scale of seconds is less than 1.2%, which is below the 0.02 mag. flickering level previously observed in the visible.

The orbital period of Scorpius X-1 has been accepted as 0.787313 d since its discovery in archival optical photometric data by Gottlieb, Wright & Liller (1975). This period has apparently been confirmed multiple times in the years since in both photometric and spectroscopic optical observations, though to date only marginal evidence has been reported for modulation of the X-ray intensity at tha...
متن کاملProduction of Millisecond Dips in Sco X-1 Count Rates by Dead Time Effects
Chang et al. (2006) reported millisecond duration dips in the X-ray intensity of Sco X-1 and attributed them to occultations of the source by small trans-Neptunian objects (TNOs). We have found multiple lines of evidence that these dips are not astronomical in origin, but rather the result of high-energy charged particle events in the RXTE PCA detectors. Our analysis of the RXTE data indicates ...
متن کاملA COMPARISON BETWEEN THERMAL AND X RADIOGRAPHY FOR STUDYING THE INTERNAL STRUCTURE OF BIOLOGICAL
ABSTRACT Background: With respect to the difference in the interaction of thermal neutron and X rays with matter, using two radiography systems of thermal neutron and X rays will yield highly valuable information for studying the inner structure of biologic samples. Methods: The high sensitivity of thermal neutron to hydrogen, in particular, has led to recognizing this system as a useful tool ...
متن کاملMillisecond dips in the RXTE/PCA light curve of Sco X-1 and TNO occultation
Millisecond dips in the RXTE/PCA light curve of Sco X-1 were reported recently (Chang et al. 2006), which were interpreted as the occultation of X-rays from Sco X-1 caused by Trans-Neptunian Objects (TNO) of hundred-meter size. Inconclusive signatures of possible instrumental effects in many of these dip events related to highenergy cosmic rays were later found (Jones et al. 2006) and the TNO i...
متن کاملThe Harmonic and Sideband Structure of the Kilohertz Quasi-Periodic Oscillations in Sco X-1
We use data from the Rossi X-ray Timing Explorer to search for harmonics and sidebands of the two simultaneous kilohertz quasi-periodic oscillations (kHz QPOs) in Sco X-1. We do not detect any of these harmonics or sidebands, with 95% confidence upper limits to their power between ∼ 1% and ∼ 10% of the power of the upper kHz QPO. The oscillations produced at these frequencies may be attenuated ...
