The blood vessels can rupture and hemorrhage ... The star enters a steady helium-burning phase which lasts about 10% of the time it spent on the main sequence (the Sun is expected to burn helium at its core for about a billion years after the helium flash). For higher mass stars, carbon collects in the core, displacing the helium to a surrounding shell where helium … See more The triple-alpha process is a set of nuclear fusion reactions by which three helium-4 nuclei (alpha particles) are transformed into carbon. See more The triple-alpha process is ineffective at the pressures and temperatures early in the Big Bang. One consequence of this is that no significant … See more With further increases of temperature and density, fusion processes produce nuclides only up to nickel-56 (which decays later to iron); heavier elements (those beyond Ni) are created mainly by neutron capture. The slow capture of neutrons, the s-process, … See more The triple-alpha process is highly dependent on carbon-12 and beryllium-8 having resonances with slightly more energy than See more Helium accumulates in the cores of stars as a result of the proton–proton chain reaction and the carbon–nitrogen–oxygen cycle.

However, the beryllium-8 ground state has almost exactly the energy of two alpha particles. In the … See more The triple-alpha steps are strongly dependent on the temperature and density of the stellar material. The power released by the reaction is … See more
WebAnd, so, there is no helium flash, just a gradual shift to a core helium burning region surrounded by a hydrogen burning shell. Horizontal Branch Stars : After helium burning begins (either explosively with a flash, or gradually for heavier stars), the star has two sources of energy, hydrogen fusion in a shell around the core and helium fusion ... WebThe stars are covered in a layer of “ash” that’s usually produced by burning helium, indicating they may have formed through collisions between other stars. SUBSCRIBE AD-FREE.
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☉ ) during their red giant phase (the Sun is predicted to experience a flash 1.2 billion years after it leaves the main sequence). A much rarer runaway helium fusion process can also occur on th…
