The masses of Population III stars [PDF]
Monthly Notices of the Royal Astronomical Society, 1989 La formation de proto-etoiles de Population III est etudiee en suivant l'hypothese que la permanence des fluctuations de masse 10-1000 M○. apres l'ere de recombinaison peut etre importante dans la fragmentation des nuages massifs de masse ∼M J pour former des etoiles de population III, ou M J est la masse de Jeans pendant l'ere de ...

On the Mass of Population III Stars [PDF]
The Astrophysical Journal, 1999 Performing 1D hydrodynamical calculations coupled with non-equilibrium processes for H2 formation, we pursue the thermal and dynamical evolution of filamentary primordial clouds and attempt to make an estimate on the mass of population III stars. It is found that, almost independent of initial conditions, a filamentary cloud continues to collapse ...

POPULATION III STARS AROUND THE MILKY WAY [PDF]
The Astrophysical Journal, 2016 ABSTRACT We explore the possibility of observing Population III (Pop III) stars, born of primordial gas. Pop III stars with masses below 0.8 M ⊙ should survive to date though are not yet observed, but the existence of stars with low metallicity as

EFFECTS OF BBN ON POPULATION III STARS [PDF]
Thinking, Observing and Mining the Universe, 2004 The presence (or absence) of CNO elements in the primordial gas determines different behaviours in population III stars formation and evolution: we therefore present an analysis of the main channels for the synthesis of these elements in BBN in order to understand, within a reliable interval, their abundance in the primordial material.

Radiative regulation of Population III star formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We explore the impact of ultraviolet (UV) radiation from massive Population III (Pop III) stars of 25, 40, 80, and 120 M_sun on the subsequent Pop III star formation. In this paper, particular attention is paid to the dependence of radiative feedback on the mass of source Pop III star.

WHERE ARE THE LOW-MASS POPULATION III STARS? [PDF]
The Astrophysical Journal, 2016 ABSTRACT We study the number and the distribution of low-mass Population III (Pop III) stars in the Milky Way. In our numerical model, hierarchical formation of dark matter minihalos and Milky-Way-sized halos are followed by a high-resolution cosmological simulation.

MAGNETIC FIELDS IN POPULATION III STAR FORMATION [PDF]
The Astrophysical Journal, 2012 We study the buildup of magnetic fields during the formation of Population III star-forming regions, by conducting cosmological simulations from realistic initial conditions and varying the Jeans resolution. To investigate this in detail, we start simulations from identical initial conditions, mandating 16, 32 and 64 zones per Jeans length, and studied

Nitrogen production in population III stars
Proceedings of the International Astronomical Union, 2022 AbstractThe first stars in the Universe have inherited their composition from primordial nucleosynthesis, so they have no metal. These stars, which are also named population III (pop III) stars, began the process of reionization in the Universe and contributed to the metal enrichment with heavy elements.
