We discuss the open charm production in peripheral reactions  $\bar pp\to \bar Y_cY_c$ and $\bar pp\to M_c\bar M_c$, where  $Y_c$ and $M_c$ stand for $\Lambda_c^+,\Sigma_c^+$ and  $D,D^*$, respectively, at $\sqrt{s}\lesssim 15$ GeV, which corresponds to theenergy range of FAIR. Our consideration is based on the topologicaldecomposition of the planar quark and diquark diagrams which allows to estimateconsistently meson and baryon exchange trajectories and energy scale parametersas well. The spin dependence is determined by the effective interaction oflowest exchanged resonance. Unknown parameters are fixed by an independentanalysis of open strangeness production in $\bar pp\to \bar YY$ and $\bar pp\to\bar KK$ reactions and of SU(4) symmetry. We present the corresponding crosssections and longitudinal double-spin asymmetries for exclusive binaryreactions with open charm mesons and baryons in the final state. Thepolarization observables have a non-trivial $t$ and $s$ dependence which issensitive to details of the open charm production mechanism.
