Abstract:
    The dynamic stability of 38 observed hierarchical triple stars with
    known orbital elements of the internal and external binary subsystems
    and component masses is considered. Four different criteria of
    dynamical stability are used. The observed stability parameters and
    their critical values are calculated by taking into account errors in
    the orbital elements and component masses.
