The identity of the primary component of capella

  • R. & R. Griffin
Article

Abstract

Ever since the discovery in 1899 that Capella is a double-lined spectroscopic binary system the sharp-lined component, which has the later spectral type, has always been regarded as the primary (more luminous) star. However, traces obtained with radial-velocity spectrometers show that the broad-lined, earlier-type component is actually the primary.
