Exploring DCO$^+$ as a tracer of thermal inversion in the disk around the Herbig Ae star HD163296 [PDF]
We aim to reproduce the DCO$^+$ emission in the disk around HD163296 using a simple 2D chemical model for the formation of DCO$^+$ through the cold deuteration channel and a parametric treatment of the warm deuteration channel.
