Parameterization of long-period eclipsing binaries

Malkov, Oleg; Kniazev, Alexei; Berdnikov, Leonid +2 more

One of the important sources for independent determination of stellar masses is eclipsing binaries with components on the main sequence, and with observable spectral lines of both components. The parameters of such stars are used to construct the mass-luminosity relation for stars of high and intermediate masses. Among them, the type of long-perio…
