Context. The nearby (∼24 pc) triple stellar system δ Velorum contains a close, eclipsing binary (Aa, Ab) discovered in 2000. Multiple systems provide an opportunity to determine the set of fundamental parameters (mass, luminosity, size, chemical composition) of coeval stars. Aims. These parameters can be obtained with particular precision in the case of eclipsing binaries; so we exploited this potential for δ Velorum’s components (Aa, Ab). Methods. We have analysed interferometric observations…
