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 …

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 Gaia mission has opened a new window into the internal kinematics of young star
clusters at the sub-km s− 1 level, with implications for our understanding of how star clusters …

Stellar multiplicity is a ubiquitous outcome of the star-formation process. The frequency and
main characteristics of multiple systems, and their dependence on primary mass and …

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 …

We present a theoretical framework in which bound stellar clusters arise naturally at the high-
density end of the hierarchy of the interstellar medium (ISM). Due to short free-fall times …

We present a novel view on the morphology and dynamical state of ten prominent, nearby
(≤ 500 pc), and young (∼ 30–300 Myr) open star clusters with Gaia DR2: α Per, Blanco 1 …

Most stars form and spend their early life in regions of enhanced stellar density. Therefore,
the evolution of protoplanetary discs (PPDs) hosted by such stars are subject to the …

Abstract The Taurus-Auriga complex is the prototypical low-mass star-forming region, and
provides a unique testbed of the star formation process, which left observable imprints on …
