Abstract Orbital motions in four hierarchical stellar systems discovered by speckle interferometry are studied. Their inner orbits relatively well constrained, while the long outer less certain. The eccentric and misaligned early-type hierarchies ϵ Cha (B9V, central star of 5 Myr old association, P = 6.4 yr, e 0.73) I 385 (A0V, ∼ 300 0.8) suggest past dynamical interactions. nearly equal masses...
