  The long-term dynamics of planetesimals in debris discs in models with
parameters of binary star systems Kepler-16, Kepler-34 and Kepler-35 with
planets is investigated. Our calculations have shown the formation of a stable
coorbital with the planet ring is possible for Kepler-16 and Kepler-35 systems.
In Kepler-34 system, significant eccentricities of the orbits of the binary and
planets can to prevent the formation of such a structure. Detection
circumbinary annular structures in observations of systems binary stars can be
evidence of the existence of planets, retaining coorbital rings from dust and
planetesimals.
