The Masses of Spectroscopic Binary Stars in the Sixth Catalogue

Masses (ℳ) have been computed for those spectroscopic binary stars in the Sixth Catalogue for which inclinations can be found from visual or eclipsing orbits, and for which absolute magnitudes can be found from visual orbits, trigonometric parallaxes or Hγ measurements. For absolute visual magnitude...

Description
Summary:Masses (ℳ) have been computed for those spectroscopic binary stars in the Sixth Catalogue for which inclinations can be found from visual or eclipsing orbits, and for which absolute magnitudes can be found from visual orbits, trigonometric parallaxes or Hγ measurements. For absolute visual magnitudes − 6 < Mυ < + 2, the (Mυ log ℳ) relationship is linear, with no systematic differences between the Hγ magnitudes and the dynamical and trigonometrical ones. For Mυ > + 4, there is slight evidence for a dual (Mυ, log ℳ) relationship. The observed (Mbol, log ℳ) relationship is in good agreement with a series of main-sequence models with (X, Y) = (0.68, 0.30).
