Charge-transfer cold Yb$^+$ + Rb collision dynamics is investigatedtheoretically using high-level {\it ab initio} potential energy curves, dipolemoment functions and nonadiabatic coupling matrix elements. Within thescalar-relativistic approximation, the radiative transitions from the entrance$A^1\Sigma^+$ to the ground $X^1\Sigma^+$ state are found to be the onlyefficient charge-transfer pathway. The spin-orbit coupling does not open otherefficient pathways, but alters the potential energy curves and the transitiondipole moment for the $A-X$ pair of states. The radiative, as well as thenonradiative, charge-transfer cross sections calculated within the $10^{-3}-10$cm$^{-1}$ collision energy range exhibit all features of the Langevin ion-atomcollision regime, including a rich structure associated with centrifugalbarrier tunneling (orbiting) resonances. Theoretical rate coefficients for twoYb isotopes agree well with those measured by immersing Yb$^+$ ion in anultracold Rb ensemble in a hybrid trap. Possible origins of discrepancy in theproduct distributions and relations to previously studied similar processes arediscussed.
