Abstract

Context. The gas and dust content of protoplanetary disks evolves over the course of a few Myr. As the stellar X-ray and UV light penetration of the disk depends sensitively on the dust properties, trace molecular species like HCO+, HCN, and CN are expected to show marked differences from photoprocessing effects as the dust content in the disk evolves.
