Wind-accreting symbiotic X-ray binaries Society. We present
a new model of the population of symbiotic X-ray binaries (SyXBs) that takes

First simultanous X-ray and optical observations of rapid variability of supercritical accretor SS433 with respect to the optical emission by approximately 80 s. Such
a delay can be interpreted as the travel time
