We use the COMA code to calculate radiative opacity coefficients for low temperature gas, where the abundances of C and N are enhanced up to a factor of 2000 with respect to a scaled solar composition. These opacities include the contributions of the most relevant atomic and molecular species. Then, by means of the FRANEC stellar evolutionary code, we compute low mass metal-poor ([Fe/H]
