In this chapter we will discuss the evolution of dust in protoplanetary disks, focusing on the
processes of grain growth and the observational consequences of this process. In the …

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 …

Terrestrial and sub-Neptune planets are expected to form in the inner (less than 10 au)
regions of protoplanetary disks. Water plays a key role in their formation,–, although it is yet …

Carbon is an essential element for life but how much can be delivered to young planets is
still an open question. The chemical characterization of planet-forming disks is a crucial step …

We present the first high-resolution sub-millimeter survey of both dust and gas for a large
population of protoplanetary disks. Characterizing fundamental properties of protoplanetary …

A new collection of photodissociation and photoionisation cross sections for 102 atoms and
molecules of astrochemical interest has been assembled, along with a brief review of the …

EX Lup is a low-mass pre-main-sequence star that occasionally shows accretion-related
outbursts. Here, we present JWST/MIRI medium-resolution spectroscopy obtained for EX …

Context. The sticking of micron-sized dust particles caused by surface forces within
circumstellar disks is the first stage in the production of asteroids and planets. The key …

We present the most sensitive 3 mm-survey to date of protoplanetary disks carried out in the
Taurus-Auriga star forming region (average rms of about 0.3 mJy), using the IRAM PdBI …

Silicate dust particles are an important player in the cosmic life cycle of matter. They have
been detected in a wide variety of environments, ranging from nearby protoplanetary disks …
