VLTI/VINCI diameter constraints on the evolutionary status of delta Eri, xi Hya, eta Boo.

Description

Using VLTI/VINCI angular diameter measurements, we constrain the evolutionary status of three asteroseismic targets: the stars $\delta$ Eri, $\xi$ Hya, $\eta$ Boo. Our predictions of the mean large frequency spacing of these stars are in agreement with published observational estimations. Looking without success for a companion of $\delta$ Eri we doubt on its classification as an RS CVn star.
