Recent theoretical investigations have suggested that the formation of the very first stars, forming out of metal-free gas, was fundamentally different from the present-day case. The question then arises which effect was responsible for this transition in the star formation properties. In this paper, we study the effect of metallicity on the evolution of the gas in a collapsing dark matter mini-halo. We model such a system as an isolated 3σ peak of mass that collapses at , using smoothed…

The formation of the first stars out of metal-free gas appears to result in stars at least an order of magnitude more massive than in the present-day case. We here consider what controls the

The role of HD cooling in primordial star formation

The role of HD cooling in the formation of primordial objects is examined by means of a great number of 1-D models of the collapse of halos, exploring a wide range of masses and virialization


The theory for the formation of the first population of stars (Pop. III) predicts an initial mass function (IMF) composed predominantly of high-mass stars, in contrast to the present-day IMF, which

High-redshift formation and evolution of central massive objects - I. Model description

Galactic nuclei host central massive objects either in the form of supermassive black holes or in the form of nuclear stellar clusters. Recent investigations have shown that both components co-exist

Star Formation at Very Low Metallicity. II. On the Insignificance of Metal-Line Cooling During the Early Stages of Gravitational Collapse

We study the influence of low levels of metal enrichment on the cooling and collapse of ionized gas in small protogalactic halos using three-dimensional, smoothed particle hydrodynamics simulations.

Did Massive Primordial Stars Preenrich the Lyα Forest?

We examine the dynamical evolution and statistical properties of the supernova ejecta of massive primordial stars in a cosmological framework to determine whether this first population of stars could

Feedback from the First Supernovae in Protogalaxies: The Fate of the Generated Metals

We investigate the chemodynamic effects of multiple supernova (SN) explosions in the central region of primordial galaxies (e.g., M ~ 108 M☉ halo at z ~ 10) using three-dimensional hydrodynamic

The implications of dust for high-redshift protogalaxies and the formation of binary disks

Numerical simulations suggest that the first galaxies are formed in protogalactic halos with virial temperatures >= 10(4) K. It is likely that such halos are polluted with trace amounts of metals

The first stars: formation of binaries and small multiple systems

We investigate the formation of metal-free, Population III (Pop III), stars within a minihalo at z ~ 20 with a smoothed particle hydrodynamics (SPH) simulation, starting from cosmological initial

The First Supernova Explosions: Energetics, Feedback, and Chemical Enrichment

We perform three-dimensional smoothed particle hydrodynamics simulations in a realistic cosmological setting to investigate the expansion, feedback, and chemical enrichment properties of a 200 M☉



Forming the First Stars in the Universe: The Fragmentation of Primordial Gas

This work investigates the fragmentation properties of metal-free gas in the context of a hierarchical model of structure formation and finds that the gas dissipatively settles into a rotationally supported disk that has a very filamentary morphology.

First Structure Formation. I. Primordial Star-forming Regions in Hierarchical Models

We investigate the formation of the first primordial star clusters from high-σ perturbations in a cold dark matter-dominated universe. For this purpose, we have developed a powerful two-level

The Formation and Fragmentation of Primordial Molecular Clouds

Many questions in physical cosmology regarding the thermal history of the intergalactic medium, chemical enrichment, reionization, etc., are thought to be intimately related to the nature and

Dust Formation in Primordial Type II Supernovae

We have investigated the formation of dust in the ejecta of Type II supernovae (SNe), mostly of primordial composition, to answer the question of where are the first solid particles formed in the

We assess supernova-driven pregalactic outflows as a mechanism for distributing the product of stellar nucleosynthesis over large cosmological volumes prior to the reionization epoch. Supernova (SN)
