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.
