Machine Learning Detects Multiplicity of the First Stars in Stellar Archaeology Data
In unveiling the nature of the first stars, the main astronomical clue is the elemental compositions of the second generation of stars, observed as extremely metal-poor (EMP) stars, in the Milky Way.

A Hide-and-seek Game: Looking for Population III Stars during the Epoch of Reionization through the He ii λ1640 Line [PDF]
The gas surrounding first-generation (Population III, hereafter Pop III) stars is expected to emit a distinct signature in the form of the He ii recombination line at 1640 Å(He ii λ1640).

Fast-rotating massive Population III stars as possible sources of extreme N enrichment in high-redshift galaxies [PDF]
We present an analysis of the chemical compositions in high-redshift galaxies, with a focus on the nitrogen-enhanced galaxies GN-z11 and CEERS-1019.

The Persistence of Population III Star Formation [PDF]
We present a semi-analytic model of star formation in the early universe, beginning with the first metal-free stars. By employing a completely feedback-limited star formation prescription, stars form at maximum efficiency until the self-consistently calculated feedback processes halt formation.

The evolution of accreting population III stars at 10^{-6} - 10^3 Ms yr^{-1} [PDF]
The first stars formed over five orders of magnitude in mass by accretion in primordial dark matter halos. We study the evolution of massive, very massive and supermassive primordial (Pop III) stars over nine orders of magnitude in accretion rate. We use

Formation of mass gap compact object and black hole binary from Population III stars [PDF]
We performed population synthesis simulations of Population III binary stars with Maxwellian kick velocity distribution when MGCOs (mass gap compact objects, with mass $2$–$5\,M_{\odot}$) are formed.

Formation of Massive and Wide First-star Binaries in Radiation Hydrodynamic Simulations
We study the formation of Population III stars by performing radiation hydrodynamic simulations for three different initial clouds extracted from cosmological hydrodynamic simulations.

On the Observability of Individual Population III Stars and Their Stellar-mass Black Hole Accretion Disks through Cluster Caustic Transits [PDF]
We summarize panchromatic Extragalactic Background Light data to place upper limits on the integrated near-infrared surface brightness (SB) that may come from Population III stars and possible accretion disks around their stellar-mass black holes (BHs ...

Merge or Survive: Number of Population III Stars per Minihalo [PDF]
The formation process of Population III (PopIII) stars in the mass-accretion phase is investigated by numerical experiments. The barotropic relation of primordial gas and artificial stiffening of the equation of state in very dense regions (>1015 cm−3 ...
