The fusion reaction in the sun is a multi- step process in which the hydrogen is burned into helium. \[\begin{aligned} & H_{1}^{1}+H_{1}^{1} \rightarrow H_{1}^{2}+e^{+}+v+Q_{1} \\ & e^{+}+e^{-} \rightarrow \gamma+\gamma+Q_{2} \\ & H_{1}^{2}+H_{1}^{1} \rightarrow H e_{2}^{3}+\gamma+Q_{3} \\ & H e_{2}^{3}+H e_{2}^{3} \rightarrow H e_{2}^{4}+H_{1}^{1}+H_{1}^{1}+Q_{4} \end{aligned} \] \end{tabular}
