# The circular orbit of the visual binary star with 7.3 and 7.3 magnitudes of the same spectrum (class G) is tilted to the line of sight by 45 °.

The circular orbit of the visual binary star with 7.3 and 7.3 magnitudes of the same spectrum (class G) is tilted to the line of sight by 45 °. The highest observed radial velocity of the satellite relative to the main star is 20 km / s, and the highest observed speed of the satellite is 0 “, 05 per year. The orbital period is 6 years; the orbit is circular. Determine the dimensions, parallax, mass and luminosity of each component of the system, radius The found masses are compared with what you can get from a certain luminosity and the curve “mass – absolute value”.

n = 0 “, 0084; luminosity 15 times greater than solar, diameter 3.9 times greater than solar; semi-major axis 5.7 AU, masses 2.5 times greater than the mass of the Sun. According to the curve mass – luminosity of the mass turned out would be about 2 solar masses.
