What is the P-process? The P-process, or proton-capture process, is a series of nuclear reactions that occur in stars. It plays a crucial role in the creation of certain heavy elements. Unlike the more well-known s-process and r-process, which involve neutron captures, the P-process involves the capture of protons by atomic nuclei. This process typically happens in supernovae, where the intense heat and pressure allow for such reactions. Understanding the P-process helps scientists learn more about the origins of elements found on Earth and throughout the universe. Dive into these 28 fascinating facts to uncover the mysteries of the P-process!
