Relying on the quantum tunneling concept and the Maxwell-Boltzmann-Gibbs statistics, Gamow shows that the star burning process happens at temperatures comparable to a critical value, called the Gamow temperature (\(\texttt{T}\)) and less than the prediction of the classical framework. In order to highlight the role of the equipartition theorem in the Gamow argument, a thermal length scale is defined and thereinafter, the effects of non-extensivity on the Gamow temperature have been investigated focusing on the Tsallis and Kaniadakis statistics. The results attest that while the Gamow temperature decreases in the framework of the Kaniadakis statistics, it can be bigger or smaller than \(\texttt{T}\) when the Tsallis statistics is employed.
