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 …

Recent observations have suggested that circumstellar disks may commonly form around
young stellar objects. Although the formation of circumstellar disks can be a natural result of …

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 …

Detecting planets in the early stages of formation is key to reconstructing the history and
diversity of fully developed planetary systems. The aim of this work is to identify potential …

Context. The specific location from where molecules emit in a protoplanetary disk depends
on the system properties. Therefore, directly constraining the emitting regions radially …

Mass-independent isotopic anomalies define two cosmochemically distinct regions: the
carbonaceous and non-carbonaceous meteorites, implying that the non-carbonaceous …

Scattered light high-resolution imaging of the protoplanetary disc orbiting HD100453 shows
two symmetric spiral arms, possibly launched by an external stellar companion. In this …

Context. Constraining the turbulence level and pebble size in protoplanetary disks is an
essential initial step in understanding the aerodynamic properties of pebbles, which are …

The structure and evolution of protoplanetary discs (PPDs) are largely governed by disc
angular momentum transport, mediated by magnetic fields. In the most observable outer …

ABSTRACT ALMA observations of line emission from planet forming discs have
demonstrated to be an excellent tool to probe the internal disc kinematics, often revealing …
