The proton–proton ( pp) fusion \ (p+p \rightarrow d+e^ {+}+ u _ {e}\), is a fundamental process in the chain of the nuclear burning of hydrogen reactions in the sun. pp putih wa The relevant temperature of the core of the sun is T \ (\sim 1. pp wa ejen ali 5 \times 10^ {7}\) K which yields thermal energy of the center of the sun in the order of a few keV (1 18 keV)
