R-process — The r process is a nucleosynthesis process occurring in core collapse supernovae (see also supernova nucleosynthesis) responsible for the creation of approximately half of the neutron rich atomic nuclei that are heavier than iron. The process… … Wikipedia
Atomic nucleus — A figurative depiction of the helium 4 atom with the electron cloud in shades of gray. In the nucleus, the two protons and two neutrons are depicted in red and blue. This depiction shows the particles as separate, whereas in an actual helium atom … Wikipedia
Table of nuclides — A chart of nuclides (cut into three parts for better presentation). A table of nuclides or chart of nuclides is a two dimensional graph in which one axis represents the number of neutrons and the other represents the number of protons in an… … Wikipedia
Halo nucleus — In nuclear physics, an atomic nucleus is called a halo nucleus or is said to have a nuclear halo if its radius is appreciably larger than that predicted by the liquid drop model, wherein the nucleus is assumed to be a sphere of constant density.… … Wikipedia
Compact star — In astronomy, the term compact star (sometimes compact object) is used to refer collectively to white dwarfs, neutron stars, other exotic dense stars, and black holes. These objects are all small for their mass. The term compact star is often… … Wikipedia
