We present extensive evolutionary models of stars with initial zero-metallicity, covering a large range of initial masses (i.e. 0:7 M M 100 M). Calculations are carried out at constant mass, with updated input physics, and applying an overshooting scheme to convective boundaries. The nuclear network includes all the important reactions of the p-p chain, CNO-cycle and -captures, and is solved by means of a suitable semi-implicit method. The evolution is followed up to the thermally pulsing AGB… 
Carbon burning in intermediate-mass primordial stars
The evolution of a zero metallicity 9 Mstar is computed, analyzed and compared with that of a solar metallicity star of identical ZAMS mass. Our computations range from the main sequence until the
Structure, Evolution, and Nucleosynthesis of Primordial Stars
The evolution of Population III stars (Z = 0) is followed from the pre-main-sequence phase up to the asymptotic giant branch (AGB) phase for intermediate-mass stars and up to C ignition in more
Zero-metallicity stars - II. Evolution of very massive objects with mass loss
We present evolutionary models of zero-metallicity very massive objects, with initial masses in the range 120 $M_{\odot}$–1000 $M_{\odot}$, covering their quiescent evolution up to central carbon
The Effect of Metallicity on the AGB Stars Evolution by Using Synthetic Model
Stars whose initial masses are between (0.89 - 8.0) M ☉ go through an Asymptotic Giant Branch (AGB) phase at the end of their life. Which have been evolved from the main sequence phase through
First stars. I. Evolution without mass loss
The first generation of stars was formed from primordial gas. Numerical simulations suggest that the first stars were predominantly very massive, with typical masses M≥100M⊙. These stars were
Structural and nucleosynthetic evolution of metal-poor & metal-free low and intermediate mass stars
We report on an investigation into stellar evolution and nucleosynthesis in the low and extremely low metallicity regime, including models of stars with a pure Big Bang composition (i.e. Z = 0). The
Grids of stellar models with rotation – V. Models from 1.7 to 120 M⊙ at zero metallicity
Understanding the nature of the first stars is key to understanding the early universe. With new facilities such as JWST we may soon have the first observations of the earliest stellar populations,
Non‐grey hydrogen burning evolution of subsolar mass Population III stars
The primordial elements, H, He and Li, are included in a low-temperature equation of state and monochromatic opacity function. The equation of state and opacity function are incorporated into the
Evolution and CNO yields of Z = 10-5 stars and possible effects on carbon-enhanced metal-poor production
Aims. Our main goals are to get a deeper insight into the evolution and final fates of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to investigate the C, N, and O yields of these
Nucleosynthesis and Evolution of Massive Metal-Free Stars
The evolution and explosion of metal-free stars with masses 10-100 M ? are followed, and their nucleosynthetic yields, light curves, and remnant masses determined. Such stars would have been the


Evolutionary sequences of stellar models with new radiative opacities. VI. $Z=0.0001$
We present a large grid of stellar evolutionary models with the initial chemical composition (Z = 0:0001;Y =0 :23). These tracks are conceived to extend the grid of stellar models described in the
Main sequence models for massive Zero-metal stars
Zero-age main-sequence models for stars of 20, 10, 5 and 2M⊙ with no heavy elements are constructed for three different possible primordial helium abundances:Y=0.00,Y=0.23, andY=0.30. The latter two
Very massive stars: Evolution with mass loss
The evolution of mass-losing very massive stars in the 500–10000M⊙ range has been investigated for two different initial compositions, (X, Z)=(0.8,0.0) and (X, Z)=(1.0,0.0). The evolutionary tracks
On the evolution of an intermediate-mass zero-metal star which does not experience thermal instabilities during the double shell burning phase
The evolution of 5 M/sub sun/ zero-metal star has been followed from the pre-main sequence to the asymptotic giant branch (AGB) phase, special attention being paid to the behavior of the nuclear
We investigate the evolution of low-mass metal-free Population III stars. Emphasis is laid upon the question of internal and external sources for CNO elements, which—if present in sufficient amounts
On the mass of population III stars
Performing one-dimensional hydrodynamical calculations coupled with nonequilibrium processes for hydrogen molecule formation, we pursue the thermal and dynamical evolution of filamentary primordial
Evolution of Low- and Intermediate-Mass Stars to the End of the Asymptotic Giant Branch with Mass Loss

An evolutionary scenario for primeval stellar populations
We present a grid of evolutionary computations of stellar structures with an original amount of heavy elements Z = 10 −10 and for an original He abundance Y = 0.23. The range of stellar masses 0.7 ≤
The First Stars
Context. The chemical composition of extremely metal-poor stars (EMP stars; [Fe/H] <∼ −3) is a unique tracer of early nucleosynthesis in the Galaxy. As such stars are rare, we wish to find classes of
Asymptotic Giant Branch Stars
Hydrostatic nucleosynthesis modifies the internal composition of low and intermediate mass stars(M <8M e) ), but only in few cases these changes may affect the overall composition of the Galaxy.
