Figure 3: The Gamow window is the range of energies where nuclear reactions occur in stars. (Top) The window is shown as the overlap region between the Maxwell Boltzmann distribution of the interacting particles and the low-energy tail of the reaction cross section. (Bottom) Typical temperature-density regimes for a variety of core and shell burning stages during stellar evolution in correlation with the Gamow energy ranges for carbon-induced reactions at these conditions.
