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 current understanding of star formation, outlining an overall theoretical framework
and the observations that motivate it. A conception of star formation has emerged in which …

Although fundamental for astrophysics, the processes that produce massive stars are not
well understood. Large distances, high extinction, and short timescales of critical …

We analyse the first giant molecular cloud (GMC) simulation to follow the formation of
individual stars and their feedback from jets, radiation, winds, and supernovae, using the …

The role of turbulence and magnetic fields is studied for star formation in molecular clouds.
We derive and compare six theoretical models for the star formation rate (SFR)—the …

This review examines the state-of-the-art knowledge of high-mass star and massive cluster
formation, gained from ambitious observational surveys, which acknowledges the multiscale …

We derive an analytic prediction for the star formation rate in environments ranging from
normal galactic disks to starbursts and ULIRGs in terms of the observables of those systems …

Star and planet formation are the complex outcomes of gravitational collapse and angular
momentum transport mediated by protostellar and protoplanetary disks. In this review, we …

We present a unified description of the scenario of global hierarchical collapse (GHC). GHC
constitutes a flow regime of (non-homologous) collapses within collapses, in which all …

Context. Thanks to its excellent 5100 m high site in Chajnantor, the Atacama Pathfinder
Experiment (APEX) systematically explores the southern sky at submillimeter wavelengths …
