The disks that orbit young stars are the essential conduits and reservoirs of material for star
and planet formation. Their structures, meaning the spatial variations of the disk physical …

Protoplanetary disks surrounding young stars are the birth place of planets. Of particular
interest are the transition disks with large inner dust cavities of tens of au, hinting at the …

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 streaming instability (SI) is a mechanism to aerodynamically concentrate solids in
protoplanetary disks and trigger the formation of planetesimals. The SI produces strong …

We present 1.3 mm continuum ALMA long-baseline observations at 3–5 au resolution of 10
of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project …

Many processes during the evolution of protoplanetary disks and during planet formation are
highly sensitive to the sizes of dust particles that are present in the disk: the efficiency of dust …

The nucleosynthetic isotope dichotomy between carbonaceous (CC) and non-
carbonaceous (NC) meteorites has been interpreted as evidence for spatial separation and …

Context. Recent observations with the Atacama Large Millimeter Array (ALMA) have shown
that the large dust aggregates observed at millimeter wavelengths settle to the midplane into …

In the past decade, ALMA observations have revealed that a large fraction of protoplanetary
discs contains rings in the dust continuum. These rings are the locations where pebbles …

Axisymmetric dust rings are a ubiquitous feature of young protoplanetary disks. These rings
are likely caused by pressure bumps in the gas profile; a small bump can induce a traffic-jam …
