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 …

Abstract Herbig Ae/Be stars are young contracting stars on the radiative track in the HR
diagram on their way to the main sequence. These stars provide a valuable link between …

Planets form and obtain their compositions in dust-and gas-rich disks around young stars,
and the outcome of this process is intimately linked to the disk chemical properties. The …

The Molecules with ALMA at Planet-forming Scales (MAPS) Large Program provides a
detailed, high-resolution (∼ 10–20 au) view of molecular line emission in five protoplanetary …

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 …

The concentric gaps and rings commonly observed in protoplanetary disks in millimeter
continuum emission have lent the impression that planet formation generally proceeds …

Molecular line observations are powerful tracers of the physical and chemical conditions
across the different evolutionary stages of star, disk, and planet formation. The high angular …

Context. Gas phase Elemental abundances in molecular CloudS (GEMS) is an IRAM 30-m
Large Program aimed at determining the elemental abundances of carbon (C), oxygen (O) …

Relating planet formation to atmospheric composition has been a long-standing goal of the
planetary science community. So far, most modeling studies have focused on predicting the …

DR Tau has been noted for its unusually high variability in comparison with other T Tauri
stars. Although it is one of the most extensively studied pre-main-sequence stars …
