Abstract

A fully relativistic evolution of 10³M_⊙ is described for initial composition of Y=Z=0. Our results show that (a) a great part of the star is in radiative equilibrium, (b) the maximal red-shift for main-sequence 10³M_⊙ stars is significantly less than for isentropic models, and (c) a very low amount of CNO elements (<10^-8 by mass) is formed at any stage before hydrogen is completely consumed and hence such stars cannot be the progenitors of Population II stars.
