The rapid photometric and spectrum variability of SS 433
Abstract
As a result of a complex quantitative analysis of spectral and photometric observations of SS433 carried out during several nights in July and August 1981 considerable rapid variations are shown to exist for the parameters Δλ(1/2), Rc, Wλ and z of the relativistic Hα- emission line components, the same parameters of the stationary He I0 lines λλ5876, 6678 (except for z), the brightness of the system in the V filter and the color index V-R, at timescales Δt = 10m - 35m (Δt = 20m). From the analysis of photometric observations of SS433 in RVB filters in 1979 it follows that the rapid variability of the object's brightness occurred practically with the same timescale. A possible interpretation of the detected variability is considered.
