Long-term X-ray studies of Scorpius X-1. I. Search for binary periodicity.
Abstract
No evidence for modulation of the Sco X-1 intensity between 3 and 6 keV at the optical period of 0.787313 day is found during one year of quasi-continuous observation. Any persistent X-ray modulation at this period must be less than one percent.
