Context. Ogata et al. (2009, Progr. Theor. Phys., 122, 1055) presented a theoretical determination of the 4He$(\alpha\alpha,\gamma)$12C, or triple-α, nuclear reaction rate. Their rate differs from the NACRE rate by many orders of magnitude at temperatures relevant for low mass stars. Aims. We explore the evolutionary implications of adopting the OKK triple-α reaction rate in low mass stars and compare the results with those obtained using the NACRE rate. Methods. The triple-α reaction rates are compared by following the evolution of stellar models at 1 and 1.5 $M_{\odot}$ with $Z = 0.0002$ and $Z = 0.02$. Results. Results show that the OKK rate has severe consequences for the late stages of stellar evolution in low...
