Abstract:
After 33 years of extensive studies of SS 433, we have learnt much
about this unique system with moving emission lines in the spectrum.
The orbital inclination is known from spectroscopic observations of
moving lines; the distance is derived from radio interferometry of
relativistic jets; the mass ratio of its components is determined from
X-ray observations of jets' eclipses. In 2005, the accretion donor was
detected as an A4-A8 giant, and its contribution to eclipse light was
measured spectroscopically. In the present paper, the A-type star was
detected via multicolor photometry on the basis of its Balmer jump. A
method is proposed to estimate the interstellar reddening, able to
measure the individual law of interstellar absorption for SS 433 from
spectrophotometry.
