This ESO workshop will focus on variability in young stellar objects and its role in the evolution of their protoplanetary disks. Specifically, addressing accretion and ejection variability and their connection to outer disk scales. Such variability is observed at the time of formation of stars and planets, two closely linked events. With the ratio of accretion to ejection still not fully understood, it remains an open question how exactly protoplanetary disks lose their mass and disperse. Since the mass budget within disks directly influences how and where planets can form, it is critical to understand and discuss results from the time-dependent nature of these environments. ESO welcomes researchers to join in May 2025.

This workshop will include the following sessions:

  • Accretion variability, long (>decades) and short (<days) across a range of amplitudes and wavelength ranges from high cadence multifilter photometry and mid-high-resolution spectroscopy.
  • Outflow variability, including disk winds and jets, observationally and theoretical studies on launching mechanisms, composition, and kinematics.
  • Accretion-outflow connection, mass flow ratios, observational challenges
  • Connection to outer disk scales, chemical composition of the disks and of the forming planets, disk substructure formation and evolution, and planet migration.
