A new spectroscopic orbit for Capella.
Abstract
Spectrograms of Capella at a dispersion of 2'4 A mm-1 were obtained at Victoria in the fall of 1973 and the spring of 1974. From them the following orbital elements were derived for the primary component: P = I04 023 (assumed), T0 = JD 2 442 , w = 292 , e = , K, = km -1, Vo = km 1 The new elements are closely similar to those derived by earlier observers. In particular, there is no indication of an increase in period that had been suggested by an analysis of earlier observations.
