Planets form and obtain their compositions in disks of gas and dust around young stars. The
chemical compositions of these planet-forming disks regulate all aspects of planetary …

Accretion through circumstellar disks plays an important role in star formation and in
establishing the properties of the regions in which planets form and migrate. The …

Abstract We present Atacama Large Millimeter/Sub-Millimeter Array (ALMA) Band 6
observations of a complete sample of protoplanetary disks in the young (∼ 1–3 Myr) Lupus …

After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

As planets form and grow within gaseous protoplanetary disks, the mutual gravitational
interaction between the disk and planet leads to the exchange of angular momentum and …

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

Context. The Mid-InfraRed Instrument (MIRI) Medium Resolution Spectrometer (MRS) on
board the James Webb Space Telescope (JWST) allows us to probe the inner regions of …

Our Sun and planetary system were born about 4.5 billion years ago. How did this happen,
and what is the nature of our heritage from these early times? This review tries to address …

Close-in super-Earths, with radii R≈ 2–5 R⊕ and orbital periods P< 100 d, orbit more than
half, and perhaps nearly all, Sun-like stars in the Universe. We use this omnipresent …

Flattened, rotating disks of cool dust and gas extending for tens to hundreds of astronomical
units are found around almost all low-mass stars shortly after their birth. These disks …
