Recent data on the production of D mesons and Λc+ baryons in heavy ion collisions at the BNL Relativistic Heavy Ion Collider and the CERN Large Hadron Collider exhibit a number of striking characteristics such as enhanced yield ratios Ds+/D0 and Λc+/D0 and their transverse momentum dependencies. In this article, we derive the momentum dependence of open charm mesons and singly charmed baryons produced in ultrarelativistic heavy ion collisions via the equal-velocity quark combination. We present analytic expressions and numerical results of yield ratios and compare them with the experimental data available. We make predictions for other charmed hadrons.
