The disks that orbit young stars are the essential conduits and reservoirs of material for star
and planet formation. Their structures, meaning the spatial variations of the disk physical …

An observational review is provided of the properties of accretion disks around young stars.
It concerns the primordial disks of intermediate-and high-mass young stellar objects in …

Context. In the past few years, there has been a rise in the detection of streamers,
asymmetric flows of material directed toward the protostellar disk with material from outside …

We present a substantial extension of the millimeter (mm) wave continuum photometry
catalog for circumstellar dust disks in the Taurus star-forming region, based on a new" …

While dust disks around optically visible, Class II protostars are found to be vertically thin,
when and how dust settles to the midplane are unclear. As part of the Atacama Large …

Gravitational forces are expected to excite spiral density waves in protoplanetary disks, disks
of gas and dust orbiting young stars. However, previous observations that showed spiral …

Gas-rich circumstellar disks are the cradles of planet formation. As such, their evolution will
strongly influence the resulting planet population. In the ESO DESTINYS large program, we …

Context. Understanding the diversity of planets requires studying the morphology and
physical conditions in the protoplanetary disks in which they form. Aims. We aim to study the …

Context. While it is generally assumed that Class II sources evolve largely in isolation from
their environment, many still lie close to molecular clouds and may continue to interact with …

Transitional disks are objects whose inner disk regions have undergone substantial
clearing. The Spitzer Space Telescope produced detailed spectral energy distributions …
