Abstract: Using VLTI/VINCI angular diameter measurements, we constrain the evolutionary status of three asteroseismic targets: the stars δEri, ξHya, ηBoo. 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 δEri, we doubt its classification as an RS CVn star.
