Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

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 …

We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

The enormous radiative and mechanical luminosities of massive stars impact a vast range of
scales and processes, from the reionization of the universe, to the evolution of galaxies, to …

Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

Star-forming gas clouds are strongly magnetized, and their ionization fractions are high
enough to place them close to the regime of ideal magnetohydrodyamics on all but the …

We study the three dimensional arrangement of young stars in the solar neighbourhood
using the second release of the Gaia mission (Gaia DR2) and we provide a new, original …

The high-precision astrometry from the second data release of the Gaia mission has made it
possible to greatly improve the census of members of nearby clusters and associations. I …

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) …

We report a series of simulations of the formation of a star cluster similar to the Orion Nebula
Cluster (ONC), including both radiative transfer and protostellar outflows, and starting from …
