International conference
of the Research Unit
"Planet Formation Witnesses and Probes: Transition Disks"

October 5-9, 2020


Transition disks, which are an advanced stage of circumstellar disks life showing evidence of an inner dust hole, are valuable witnesses of the planet formation process. DFG Research Unit FOR 2634/1 "Planet Formation Witnesses and Probes: Transition Disks" (RUTD) is focused on studying how the transition disks can be used to constrain protoplanetary disk evolution and planet formation. This conference will summarize the first funding period of the RUTD. During the conference, members of the RUTD will meet with invited international experts to exchange their scientific results and discuss areas of future development.

This conference takes part in the framework of the CAS Research Group "The Ionisation Structure of Planet Forming Discs and their Atmospheres" led by Barbara Ercolano at the Center for Advanced Studies at LMU Munich.
