Bakos, Gustav A. Abstract Photoelectric colors and magnitudes on the B, V system have been obtained for 75 visual binaries. Absolute visual magnitudes have been determined spectrographically for all the primary stars. This and the known apparent magnitude difference between the components fixed the absolute visual magnitude of the companion. Because of the selection factor the primary components of visual binaries are generally late type stars, giants or supergiants. The secondary components, with a few exceptions, are concentrated along the main sequence. This main sequence deviates slightly from the zero-age main sequence. ~Then visual binaries are considered in the light of an age sequence (as outlined by evolutionary tracks of galactic clusters) both young and old binaries are represented. A grnup of visual binaries has been identified where one (the fainter) or both components are still in the stage of gravitational contraction. For the majority of stars an age of 5 X io9 years has been postulated. However, there are indications that a few stars may be as old as 10 X I0~ years. Cases where the secondary components are situated above or below the main sequence can also be understood on the basis of stellar evolution.
