Impact of the uncertainties of $3\alpha$ and ${}^{12}\mathrm{C}(\alpha ,\gamma {)}^{16}\mathrm{O}$ reactions on the He-burning phases of low- and intermediate-mass stars

We estimate the impact on the stellar evolution of the uncertainties in the $3\alpha$ and the ${}^{12}\mathrm{C}(\alpha ,\gamma {)}^{16}\mathrm{O}$ reaction rates [...]. We calculated models of low- and inte…
