GRAVITY+: impact on star and planet formation

The deployment of the instrument GRAVITY+ at the VLTI on Cerro Paranal (ESO/Chile) planned in 2025-2026 and the recent start of science operation with the James Webb Space Telescope provide a promising opportunity to consider multi-technique, multi-wavelength approaches to obtain a detailed view of planet-forming disks at all scales around young stellar objects. We propose to organize a 3-day workshop in Grenoble on June 11-13, 2024, bringing together a community of experts in protoplanetary disks as well as in star and planet formation to elaborate joint scientific programs to be carried out with VLT/VLTI/ALMA/ELT/JWST/CFHT in the near future. We aim at fostering discussions on possible strategies that will ensure, through coordinated European and/or national initiatives, the funding and sustainability of the resources needed for the in-depth scientific exploitation of multi-instrument campaigns. The workshop will include 4 or 5 sessions introduced by invited speakers and members of the community. Contributed talks, in particular from young researchers, are welcome; round-tables and discussion slots will be organized to explore possible synergies, generate new ideas and programs, and share expertise. Registration is free of charge but compulsory. Lunches and coffee breaks will be covered by the workshop funds. Participants are responsible for their own transportation, accommodation, and dinners. The workshop will take place on the Grenoble University Campus, easily reached from Grenoble downtown by tram (about 15 min). The audience will be limited to about 50 persons for logistics reasons
