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 …

Discs of gas and dust around million-year-old stars are a by-product of the star formation
process and provide the raw material to form planets. Hence, their evolution and dispersal …

Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime
interest to understand the physical and chemical conditions under which planet formation …

Abstract The Disk Substructures at High Angular Resolution Project (DSHARP) provides a
large sample of protoplanetary disks with substructures that could be induced by young …

The disk mass is among the most important input parameter for every planet formation
model to determine the number and masses of the planets that can form. We present an …

The mass accretion rate, Ṁ acc, is a key quantity for the understanding of the physical
processes governing the evolution of accretion discs around young low-mass (M⋆≲ 2.0 …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

The σ Orionis cluster is important for studying protoplanetary disk evolution, as its
intermediate age (∼ 3–5 Myr) is comparable to the median disk lifetime. We use ALMA to …

Context. Transition disks are protoplanetary disks with dust-depleted cavities, possibly
indicating substantial clearing of their dust content by a massive companion. For several …

Transition disks with large inner dust cavities are thought to host massive companions.
However, the disk structure inside the companion orbit and how material flows toward an …
