SUMMARY:Protoplanetary disk evolution: the key to planet formation
DESCRIPTION:The evolution of protoplanetary disks in young stellar clusters is regulated by the interplay of various physical processes\, such as accretion and winds\, and by the interactions with other stars in the cluster. Accretion and winds are best studied spectroscopically. Instruments like the VLT/X-Shooter spectrograph allow us to observe simultaneously the signatures of the accretion process\, such as the UV-excess and the emission lines\, together with lines tracing winds and outflows\, such as helium lines and forbidden lines. At the same time\, these spectra allow us to robustly derive the physical parameters of the central objects\, such as their temperature and their mass. These processes relate to the disk mass and size\, which can nowadays be studied with ALMA. Finally\, the coming Gaia data releases will open the field to new studies of dynamical evolution of stars in young clusters by means of kinematical modelling.\nI will report on the stellar\, accretion\, and wind properties derived with X-Shooter of the complete samples of low-mass stars in the Lupus and Chamaeleon star forming regions\, and discuss the dependence of stellar and accretion parameters with the disk properties obtained with ALMA surveys in these regions. I will present the results of the study of some peculiar dipping young stars recently discovered. Finally\, I will show how we can use Gaia data to study young clusters and the effect of interactions on the evolution of disks.
