The mass distribution of Population III stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 Extremely metal-poor (EMP) stars are uniquely informative on the nature of massive Population III stars. Modulo a few elements that vary with stellar evolution, the present-day photospheric abundances observed in EMP stars are representative of their natal gas cloud composition.

Gravitational Wave Background from Population III Stars [PDF]
AIP Conference Proceedings, 2007 We estimate the gravitational wave (GW) background from Population III (Pop III) stars using the results from our hydrodynamic simulations (Suwa et al. 2007). We calculate gravitational waveforms from matter motions and anisotropic neutrino emissions for single Pop III stars.

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.

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

Evolution of Low‐Mass Population III Stars [PDF]
The Astrophysical Journal, 2007 We present the evolutionary models of metal-free stars in the mass range from 0.8 to 1.2 Msun with up-to-date input physics. The evolution is followed to the onset of hydrogen mixing into a convection, driven by the helium flash at red giant or asymptotic giant branch phase.

Diffuse cosmic neutrino background from population III stars [PDF]
Astroparticle Physics, 2005 We study the expected diffuse cosmic neutrino flux produced by Population III (PopIII) stars during their nuclear burning phases as well as from their final stages of evolution (core collapse). Assuming a fraction f_III=10^(-3) of all baryons forms PopIII stars, our flux estimate is comparable to the diffuse neutrino flux produced by the ordinary stars

The most massive Population III stars
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Recent data from the JWST suggest that there are realistic prospects for detecting the earliest generation of stars at redshift ∼20. These metal-poor, gaseous Population III (Pop III) stars are likely in the mass range $10\!-\!10^3\, {\rm M}_{\odot }$ .

Magnetorotational Collapse of Population III Stars [PDF]
Publications of the Astronomical Society of Japan, 2007 Abstract We performed a series of two-dimensional magnetorotational core-collapse simulations of Population III stars. Changing the initial distributions of the rotation and magnetic fields prior to collapse in a parametric manner, we computed 19 models.

Magnetohydrodynamics of Population III Star Formation [PDF]
AIP Conference Proceedings, 2010 The evolution of collapsing primordial clouds and the formation of Population III (Pop III) protostars are investigated with three‐dimensional ideal MHD simulations. We follow the collapse of parsec‐sized primordial clouds down to the formation of protostars on sub‐AU scales.
