Revised masses of α Centauri.
POURBAIX D., NEUFORGE-VERHEECKE C. and NOELS A.
Abstract (from CDS):
With the precise radial velocities lately published (Murdoch et al., 1993Obs...113...79M) a simultaneous least-squares adjustment of all visual and spectroscopic observations of the α Centauri system is now possible and likely to yield some accurate information. Such an orbit determination leads to a mass ratio in agreement with the astrometric estimate of Kamper & Wesselink (1978AJ.....83.1653K) but yields upward revisions of the distance and masses. We examine the effects these revisions on the evolutionary status of the system.
