[en] With the precise radial velocities lately published \cite{Murdoch-1993:b}, a simultaneous least-squares adjustment of all visual and spectroscopic observations of the alpha 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 \cite*{Kamper-1978} but yields upward revisions of the distance and masses. We examine the effects these revisions on the evolutionary status of the system.
