Abstract
The study computes evolutionary tracks for 13-16 mass values (depending on the assumed chemical composition) in the range 0.15-1.25 solar mass for each of 10 metallicities between -2.26 and -0.47 (Fe/H). A total of 46 tracks are evolved to the helium flash point. The properties of selected models along the entire evolutionary sequences for 0.8 solar mass (or 0.85 in the case of the three highest (Fe/H) values) are tabulated in detail. For all of the computed giant branch tracks, such information as the luminosity and core mass at the helium flash, the final C-12/C-13 and C/N number abundance ratios obtained on completion of the first dredge-up phase, and the luminosity where the H-burning shell contacts the chemical composition discontinuity produced when the convective envelope reaches its maximum penetration is also provided for critical comparisons with observations.
