Context. The Galactic microquasar SS 433 launches oppositely-directed jets at speeds approximately a quarter of the speed of light. Both the speed and direction of the jets exhibit small fluctuations. A component of the speed variation has 13 day periodicity and the orbital phase at which its maximum speed occurs has advanced approximately 90° in 25 years. Aims. To examine the possibility that these variations are associated with a mildly eccentric orbit and conditions necessary to achieve this… Expand
More on the circumbinary disk of SS 433
Context. Certain lines in spectra of the Galactic microquasar SS 433, in particular the brilliant Balmer Hα line, have been interpreted as emission from a circumbinary disk. In this interpretationExpand
Yet more on the circumbinary disk of SS 433 (Research Note)
Context. Certain lines in spectra of the Galactic microquasar SS 433, in particular the Hα line and He I, have been interpreted as emission from a circumbinary disk. In this interpretation theExpand
On the Formation of SS433
SS433 is an extraordinary X-ray binary which is ejecting bipolar jets with $26\%$ of the speed of light. Associated with the supernova-like shell W50, SS433 is also probably one of the youngest X-rayExpand

Fluctuations and symmetry in the speed and direction of the jets of SS 433 on different timescales
Context. The Galactic microquasar SS 433 launches oppositely-directed plasma jets at speeds approximately a quarter of the speed of light along an axis which precesses, tracing out a cone of polarExpand
Transient and secular variations of the moving-line spectra from SS 433
A dynamical model has been developed which accounts for variations in the motion of the jets of SS 433, including apsidal motion and secular effects on the orbital period. For the apsidal motion, aExpand
Symmetry in the Changing Jets of SS 433 and Its True Distance from Us
We present the deepest yet radio image of the Galactic jet source SS 433, which reveals over two full precession cycles (>2 × 163 days) of the jet axis. Systematic and identifiable deviations fromExpand
SS 433: Observation of the Circumbinary Disk and Extraction of the System Mass
The so-called stationary Hα line of SS 433 is shown to consist of three components. A broad component is identified as emitted in that wind from the accretion disk that grows in speed with elevationExpand

We present a reanalysis of the optical spectroscopic data on SS 433 from the last quarter-century and demonstrate that these data alone contain systematic and identifiable deviations from theExpand
On the origin of X-ray variability of SS 433
The X-ray flares observed from the central source in SS 433 by the Einstein telescope are attributed to surges in the mass transfer rate due to changes in the critical Roche volume of the companion.Expand

The central region in SS433 supercritical disk and origin of flares
Mean orbital light curves of SS433 in different precessional phases are analysed for active and passive states separately. In passive states the mean brightness depends strongly on the diskExpand
