Scientific paper

A classification of dynamical states has been proposed for triple systems; the most important of their characteristics are the total energy Etr and the relative pair energies Eb of the bodies in these systems. For eight triple stars (ADS 1630, 2926, 6175, 6650, 6811, 7114, 9626 and 9909) probabilities of the dynamical states and the values Etr±σEtr and Eb±σEb have been obtained by statistical tests. Only three triple stars, namely ADS 1630 (r ≡ 80 pc), 6175 (r ≡ 14 pc) and 9909 (r ≡ 22 pc), appear to be surely physical systems.
