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 …

Abstract Herbig Ae/Be stars are young contracting stars on the radiative track in the HR
diagram on their way to the main sequence. These stars provide a valuable link between …

We present an overview of the Large Program," Early Planet Formation in Embedded Disks
(eDisk)," conducted with the Atacama Large Millimeter/submillimeter Array (ALMA). The …

High dust density in the midplane of protoplanetary disks is favorable for efficient grain
growth and can allow fast formation of planetesimals and planets, before disks dissipate …

Geochemical and astronomical evidence demonstrates that planet formation occurred in two
spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We …

Astronomical observations reveal that protoplanetary disks around young stars commonly
have ring-and gap-like structures in their dust distributions. These features are associated …

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 …

Planet-forming disks are not isolated systems. Their interaction with the surrounding medium
affects their mass budget and chemical content. In the context of the ALMA-DOT program …

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 …
