Abstract

We analyze the radial distribution of DCO^+^ in the protoplanetary disk around HD 169142, a Herbig Ae type star, with the aim of determining possible formation scenarios of DCO^+^. Using a simple chemical model, we investigate the effect of gas-phase CO abundance and gas temperature on the production of DCO^+^ near the disk midplane. Model fits to the DCO^+^ radial profile suggest a much colder disk midplane than the disk physical structure obtained from the literature.
