  Solar-like oscillations detected in both components of the binary system
alpha Centauri provide strong constraints on the fundamental parameters of the
stellar system. We model alpha Centauri by means of a Levenberg-Marquardt
minimization algorithm including seismic and classical constraints.
Computations, that were perfomed decreasing significanly the weight of alpha
Cen B seismic data in the calibration procedure, predict small separations in
good agreement with new observations of solar-like oscillations in alpha Cen B
by Bedding (these proceedings).
