Abstract (from CDS):
Models of α Cen A & B have been computed using the masses determined by Pourbaix et al. 2002A&A...386..280P) and the data derived from the spectroscopic analysis of Neuforge & Magain (1997A&A...328..261N). The seismological data obtained by Bouchy & Carrier (2001A&A...374L...5B, 2002A&A...390..205B]) do help improve our knowledge of the evolutionary status of the system. All the constraints are satisfied with a model which gives an age of about 6Gyr for the binary.
