使用VLTI/芬奇角直径测量，我们约束了三个小行星地震目标的演化状态：δ Eri、ξ Hya、η Boo星。我们对这些恒星的平均大频率间隔的预测与已发表的观测估计一致。由于没有成功地寻找到Eri δ的伴星，我们怀疑它是否属于RS CVn型星星。
Using VLTI/VINCI angular diameter measurements, we constrain the evolutionary status of three asteroseismic targets: the stars δ Eri, ξ Hya, η 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 δ Eri, we doubt its classification as an RS CVn star.
