Extremely Metal-Poor Asymptotic Giant Branch Stars
Universe, 2022 Little is known about the first stars, but hints on this stellar population can be derived from the peculiar chemical composition of the most metal-poor objects in the Milky Way and in resolved stellar populations of nearby galaxies.

Merger Conditions of Population III Protostar Binaries
The Astrophysical Journal, 2023 Massive close binary stars with extremely small separations have been observed, and they are possible progenitors of gravitational-wave sources. The evolution of massive binaries in the protostellar accretion stage is key to understanding their formation

The Astronomical Journal, 2022 Population III stars were the first stars to form after the Big Bang and are believed to have made the earliest contribution to the metal content of the universe beyond the products of the Big Bang nucleosynthesis.

Evolution of Massive Population III Stars
Acta Polytechnica CTU Proceedings, 2014 While the evolution of massive stars in the local Universe is dominated by mass-loss, the evolution of massive Population III stars should be dominated by rotation.

Following the Cosmic Evolution of Pristine Gas III: The Observational Consequences of the Unknown Properties of Population III Stars [PDF]
, 2019 We study the observational consequences of several unknown properties of Population III (Pop III) stars using large-scale cosmological simulations that include a subgrid model to track the unresolved mixing of pollutants.

Machine Learning Detects Multiplicity of the First Stars in Stellar Archaeology Data
The Astrophysical Journal, 2023 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.

Formation of Massive and Wide First-star Binaries in Radiation Hydrodynamic Simulations
The Astrophysical Journal, 2023 We study the formation of Population III stars by performing radiation hydrodynamic simulations for three different initial clouds extracted from cosmological hydrodynamic simulations.

The search for Population III stars [PDF]
, 2008 Population III stars, the first generation of stars formed from primordial Big Bang material with a top-heavy IMF, should contribute substantially to the Universe reionization and they are crucial for understanding the early metal enrichment of galaxies.

The Impact of Patchy Reionization on Ultrafaint Dwarf Galaxies
The Astrophysical Journal, 2023 We investigate how patchy reionization affects the star formation history (SFH) and stellar metallicity of ultrafaint dwarf galaxies (UFDs). Patchy reionization refers to varying ultraviolet background strengths depending on a galaxy’s environment ...

On the Mass of Population III Stars [PDF]
, 1998 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.
