Recent numerical simulations have suggested the probability of a fraction of the primordial stars being ejected from the cluster of their origin. We explore the possibility that some of these can remain on the main sequence until the present epoch. We develop a semianalytical model guided by results of cosmological simulations to study the mass accretion by these protostars as a function of the original stellar mass and other parameters such as angular momentum and gravitational drag due to… 
Metal-poor Stars Observed with the Southern African Large Telescope II. An Extended Sample
We present results from high-resolution (R ∼ 40,000) spectroscopic observations of over 200 metal-poor stars, mostly selected from the RAVE survey, using the Southern African Large Telescope. We were

The chemical signature of surviving Population III stars in the Milky Way
Cosmological simulations of Population (Pop) III star formation suggest that the primordial initial mass function may have extended to sub-solar masses. If Pop III stars with masses < 0.8 M_Sun did
The Formation of Population III Binaries from Cosmological Initial Conditions
TLDR
A cosmological simulation in which the central 50 M⊙ clump breaks up into two cores having a mass ratio of two to one, with one fragment collapsing to densities of 10−8 grams per cubic centimeter is discussed.
Protostar Formation in the Early Universe
TLDR
An ab initio computer simulation of the formation of primordial stars that follows the relevant atomic and molecular processes in a primordial gas in an expanding universe shows that primeval density fluctuations left over from the Big Bang can drive the formation from a tiny protostar to a massive primordial star.
The Birth of a Massive First-star Binary
We study the formation of massive Population III binary stars using a newly developed radiation hydrodynamics code with the adaptive mesh refinement and adaptive ray-tracing methods. We follow the

Effect of interstellar objects on metallicity of low-mass first stars formed in a cosmological model
We investigate metal pollution onto the surface of low-mass population III stars (Pop. III survivors) via interstellar objects floating in the Galactic interstellar medium. Only recently, Tanikawa et
