burst of neutrons
21Étoile à neutron — Étoile à neutrons RX J1856.4 3754, une étoile à neutrons isolée proche du Système solaire, dont l émission de surface est vue par le télescope spatial Hubble. Une étoile à neutrons est le nom donné à un astre principalement composé de neutrons… …
22Neutrino — For other uses, see Neutrino (disambiguation). Neutrino/Antineutrino The first use of a hydrogen bubble chamber to detect neutrinos, on November 13, 1970. A neutrino hit a proton in a hydrogen atom. The collision occurred at the point where three …
23Compact 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… …
24atomic bomb — 1. a bomb whose potency is derived from nuclear fission of atoms of fissionable material with the consequent conversion of part of their mass into energy. 2. a bomb whose explosive force comes from a chain reaction based on nuclear fission in U… …
25Nuclear drip line — In nuclear physics, the boundaries for nuclear particle stability are conceptualized as drip lines. The nuclear landscape is understood by plotting boxes, each of which represents a unique nuclear species, on a graph with the number of neutrons… …
26Mushroom cloud — created by smoke billows Ascending cloud from Redoubt Vol …
27Fusion power — The Sun is a natural fusion reactor. Fusion power is the power generated by nuclear fusion processes. In fusion reactions two light atomic nuclei fuse together to form a heavier nucleus (in contrast with fission power). In doing so they release a …
28Neutrino detector — The Sudbury Neutrino Observatory, a 12 meter sphere filled with heavy water surrounded by light detectors located 2000 meters below the ground in Sudbury, Ontario, Canada. A neutrino detector is a physics apparatus designed to study neutrinos.… …
29Teller–Ulam design — The basics of the Teller–Ulam design. Radiation from a primary fission bomb compresses a secondary section containing both fission and fusion fuel. The compressed secondary is heated from within by a second fission explosion. The Teller–Ulam… …
30Modern searches for Lorentz violation — Important motivations for modern searches for Lorentz violation are deviations from Lorentz invariance (and thus special relativity) predicted by some variations of quantum gravity, string theory, and some alternatives to general relativity.… …
