    An updated version of the game, titled Dengeki Bunko: Fighting Climax Ignition (電撃文庫 FIGHTING CLIMAX IGNITION, Dengeki Bunko Faitingu Kuraimakkusu Igunishion), was released in July 2015. [7] The update contains additional characters and more balanced gameplay.

  3. Liquid helium - Wikipedia

    en.wikipedia.org/wiki/Liquid_helium

    Liquid helium is a physical state of helium at very low temperatures at standard atmospheric pressures.Liquid helium may show superfluidity.. At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −269 °C (−452.20 °F; 4.15 K).

  4. Red-giant branch - Wikipedia

    en.wikipedia.org/wiki/Red-giant_branch

    For stars with a degenerate helium core, there is a limit to this growth in size and luminosity, known as the tip of the red-giant branch, where the core reaches sufficient temperature to begin fusion. All stars that reach this point have an identical helium core mass of almost 0.5 M ☉, and very similar stellar luminosity and temperature ...

    Destiny sold 91,277 physical retail copies for PlayStation 4 and 49,503 retail copies for PlayStation 3 within the first week of release in Japan, placing second and third place respectively within the Japanese software sales charts for that particular week. [190] Destiny was the third best-selling retail game in the United States in 2014. [191]

  6. Triple-alpha process - Wikipedia

    en.wikipedia.org/wiki/Triple-alpha_process

    As a side effect of the process, some carbon nuclei fuse with additional helium to produce a stable isotope of oxygen and energy: 12 6 C + 4 2 He → 16 8 O + γ (+7.162 MeV) Nuclear fusion reactions of helium with hydrogen produces lithium-5, which also is highly unstable, and decays back into smaller nuclei with a half-life of 3.7 × 10 −22 s.

  7. Helium flash - Wikipedia

    en.wikipedia.org/wiki/Helium_flash

    A helium flash is a very brief thermal runaway nuclear fusion of large quantities of helium into carbon through the triple-alpha process in the core of low-mass stars (between 0.8 solar masses (M ☉) and 2.0 M ☉ [1]) during their red giant phase. The Sun is predicted to experience a flash 1.2 billion years after it leaves the main sequence.

  8. Hypergolic propellant - Wikipedia

    en.wikipedia.org/wiki/Hypergolic_propellant

    Hypergolically-fueled rocket engines are usually simple and reliable because they need no ignition system. Although larger hypergolic engines in some launch vehicles use turbopumps, most hypergolic engines are pressure-fed. A gas, usually helium, is fed to the propellant tanks under pressure through a series of check and safety valves.

    en.wikipedia.org/wiki/Software_bug

    A software bug is a design defect in computer software.A computer program with many or serious bugs may be described as buggy.. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing).
