Abstract :In this study, the effects of the energy generation rates of Triple Alpha and CNO nuclear reactions on the evolution of Main sequence star models with masses in the range of 0.65-1.2 Mʘ are investigated. Paczynski\'s GOB, SCH and HB7 star model programs are used for each model. The ages of stars are calculated using the original NACRE (Nuclear Astrophysics Compilation of Reactions) energy generation rates and NACRE rates reduced by ten percent. The ages of the current IT Cas and V636 Cen stars are calculated and compared with the results in the literature. Since Triple Alpha reactions are very difficult to perform in terrestrial laboratories, this theoretical model study will shed light on observational studies of low-mass and even massive stars.
