Since Protostars and Planets VI (PPVI), our knowledge of the global properties of
protoplanetary and debris disks, as well as of young stars, has dramatically improved. At the …

Proto-planetary discs, the birth environment of planets, are an example of a structure
commonly found in astrophysics, accretion discs. Identifying the mechanism responsible for …

Our understanding of planet formation has been rapidly evolving in recent years. The
classical planet formation theory, developed when the only known planetary system was our …

The evolution of protoplanetary discs and the related process of planet formation is
regulated by angular momentum transport and mass-loss processes. Over the past decade …

The size of a disk encodes important information about its evolution. Combining new
Submillimeter Array observations with archival Atacama Large Millimeter/submillimeter …

Planet-forming disc evolution is not independent of the star formation and feedback process
in giant molecular clouds. In particular, OB stars emit UV radiation that heats and disperses …

MHD models and the observation of accretion streamers confirmed that protostars can
undergo late accretion events after the initial collapse phase. To provide better constraints …

The final architecture of planetary systems depends on the extraction of angular momentum
and mass-loss processes of the discs in which they form. Theoretical studies proposed that …

The connection between the nature of a protoplanetary disk and that of a debris disk is not
well understood. Dust evolution, planet formation, and disk dissipation likely play a role in …

ABSTRACT A key problem in protoplanetary disc evolution is understanding the efficiency of
dust radial drift. This process makes the observed dust disc sizes shrink on relatively short …
