Daily radio variability of X-rays binaries with relativistic jets

We discussed several long daily monitoring programs with the RATAN-600 radio telescope of the sources: SS433, Cyg X-3, LSI +61.303 deg, GRS 1915+10 at 122 GHz. We confirmed the correlation flaring radio emission of Cyg X-3 with hard X-ray emission and the anticorrelation with soft X-ray emission during the strong flare ( > 3 Jy) in May 1997. Powerful flaring events of SS433 were detected at six frequencies in May 1996 and in May 1999. We first detected 6.044-0.06 day modulation at level 10-15 percent from the quiet flux density of SS433, which could be associated with Doppler boosting in 0.26c-moving precessing and nodding jets with discrete condensations. Two flaring events near phase 0.6 of the 26.5-day orbital period have been detected for first time at four frequencies simultaneously for the remarkable X-binary LS I + 61.303 deg in 1998. (Author)
