Scientific paper

Radial-velocity spectrometer measurements of both components of the double-line Capella system have been combined with earlier radial-velocity measurements from four previous studies to produce an improved double-line orbit. The resulting mass ratio M1/M2 = 1.18±0.02 differs by only 2% from the virtually ignored previous determination by W. Struve (1939). Combining the new radial-velocity elements with McAlister's (1981) recent interferometric orbit allows the determination of the individual masses of M1 = 3.31±0.08 M_sun; and M2 = 2.80±0.05 M_sun;. This mass difference is perhaps too great for both stars to be on the first crossing of the Hertzsprung gap as proposed by Boesgaard (1971).
