The first generation of stars, often called Population III (or Pop III), form from metal-free
primordial gas at redshifts z∼ 30 and below. They dominate the cosmic star-formation …

Stars are among the most fundamental structures of our Universe. They comprise most of the
baryonic and luminous mass of galaxies; synthesize heavy elements; and inject mass …

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 …

We present results from the first population synthesis study of protostellar discs. We analyse
the evolution and properties of a large sample of protostellar discs formed in a radiation …

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 …

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 …

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 …

The stellar initial mass function (IMF) in the early universe is essential to understand the
formation of ancient galaxies. To this end, we conduct a series of long-term radiation …

We study star cluster formation in a low-metallicity environment using three-dimensional
hydrodynamic simulations. Starting from a turbulent cloud core, we follow the formation and …

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