Since Protostars and Planets VI (PPVI), our knowledge of the global properties of
protoplanetary and debris disks, as well as of young stars, has dramatically improved. At the …

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 …

MHD models and the observation of accretion streamers confirmed that protostars can
undergo late accretion events after the initial collapse phase. To provide better constraints …

High spatial resolution CO observations of midinclination (≈ 30–75) protoplanetary disks
offer an opportunity to study the vertical distribution of CO emission and temperature. The …

Constraining the physical and chemical structure of young embedded disks is crucial for
understanding the earliest stages of planet formation. As part of the Early Planet Formation …

Abstract We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of
the Class I source Oph IRS 63 in the context of the Early Planet Formation in Embedded …

We present an ACA search for [C i] 1–0 emission at 492 GHz toward large T Tauri disks (gas
radii≳ 200 au) in the∼ 1–3 Myr-old Lupus star-forming region. Combined with Atacama …

Surveys of star-forming regions reveal that the dust mass of protoplanetary discs decreases
by several orders of magnitude on timescales of a few million years. This decrease in the …

Context. The evolution of protoplanetary disks is regulated by an interplay of several
processes, either internal to the system or related to the environment. As most of the stars …

High-spatial-resolution observations of CO isotopologue line emission in protoplanetary
disks at mid-inclinations (≈ 30–75) allow us to characterize the gas structure in detail …
