The X-ray, optical, and radio behavior of Scorpius X-1: the 1971 coordinated observations.
Abstract
Scorpius X-1 has been monitored at radio, optical, and X-ray wavelengths for 21 days during the period 1971 February 23 through 1971 April 2. The Uhuru satellite was used for the X-ray observations. The X-ray intensity was found to fluctuate rapidly (time constants <6 minutes) by a factor of about 2 during periods when the object was in a bright and flaring optical state. The X-ray flux was constant to within 5 percent during the faint and relatively quiescent optical periods. No correlation between the X-ray/optical activity and radio flaring was noted.
