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 …

Planets form in disks of gas and dust around young stars. The disk molecular reservoirs and
their chemical evolution affect all aspects of planet formation, from the coagulation of dust …

Protoplanetary disks are known to possess a variety of substructures in the distribution of
their millimetre-sized grains, predominantly seen as rings and gaps, which are frequently …

We still do not understand how planets form or why extrasolar planetary systems are so
different from our own Solar System. However, the past few years have dramatically …

We present the discovery of a spatially unresolved source of submillimeter continuum
emission (λ= 855 μm) associated with a young planet, PDS 70 c, recently detected in Hα …

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 …

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 …

At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii
and orbital periods of less than 100 days. We use N-body simulations including a model for …

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 …

Context. Imaged in the gap of a transition disk and found at a separation of about 195 mas (~
22 au) from its host star at a position angle of about 155°, PDS 70 b is the most robustly …
