Chemistry in Disks. IX. Observations and modeling of HCO+ and DCO+ in DM Tau

Richard Teague, Dmitry Semenov, Stephane Guilloteau +5

We present resolved Plateau de Bure Array observations of DM Tau in lines of HCO+ (3-2), (1-0) and DCO+ (3-2). A power-law fitting approach allowed a derivation of column densities…
