From nuclear clusters to neutron stars
WebThe synthesis of elements heavier than iron mostly takes place through neutron-capture processes. Depending on the reaction timescales of neutron captures, two main processes can be distinguished: the slow (s) process (see Käppeler et al. [] for a review) and the rapid (r) process (see Cowan et al. [] for a review).The s-process takes place under relatively … WebFeb 24, 2024 · Neutron stars are created when giant stars die in supernovas and their cores collapse, with the protons and electrons essentially melting into each other to form neutrons.
