  2. Helium flash - Wikipedia

    en.wikipedia.org/wiki/Helium_flash

    In the case of normal low-mass stars, the vast energy release causes much of the core to come out of degeneracy, allowing it to thermally expand. This consumes most of the total energy released by the helium flash, [2] and any left-over energy is absorbed into the star's upper layers. Thus the helium flash is mostly undetectable by observation ...

    Has a key role in Star Trek's warp drive propulsion system, since it is described as the only compound able to generate warp fields when given energy from the warp core. The crew of USS Voyager are forced to land on a planet to retrieve verterium cortenide to repair their warp nacelles after a sabotage. Vibranium: Marvel Comics

  4. Solar core - Wikipedia

    en.wikipedia.org/wiki/Solar_core

    The core produces almost all of the Sun's heat via fusion; the rest of the star is heated by the outward transfer of heat from the core. The energy produced by fusion in the core, except a small part carried out by neutrinos, must travel through many successive layers to the solar photosphere before it escapes into space as sunlight, or else as ...

  5. Control rod - Wikipedia

    en.wikipedia.org/wiki/Control_rod

    Control rods often stand vertically within the core. In PWRs they are inserted from above, with the control rod drive mechanisms mounted on the reactor pressure vessel head. In BWRs, due to the necessity of a steam dryer above the core, this design requires insertion of the control rods from beneath.

    Nuclear fuel process A graph comparing nucleon number against binding energy Close-up of a replica of the core of the research reactor at the Institut Laue-Langevin. Nuclear fuel refers to any substance, typically fissile material, which is used by nuclear power stations or other nuclear devices to generate energy.

  8. Perimeter (video game) - Wikipedia

    en.wikipedia.org/wiki/Perimeter_(video_game)

    A building that loses connection to the power grid stops working and may be captured by an enemy player who connects it to their own Energy Core network. Thus destroying Energy Cores to disconnect parts of an enemy's base is a possible strategy on certain maps. Energy Cores also produce energy, the game's only resource. The amount of energy ...

  9. Quantum chaos - Wikipedia

    Note that energy levels can cross due to underlying symmetries of dynamical motion. [4] Computed chaotic Rydberg atom energy level spectra of lithium in an electric field near n=15. Note that energy levels cannot cross due to the ionic core (and resulting quantum defect) breaking symmetries of dynamical motion. [4]
