Helium burning color
In a very low-mass star (less than about 0.5 M☉ ), the core is never hot enough to ignite helium. The degenerate helium core will keep on contracting, and finally becomes a helium white dwarf . The helium flash is not directly observable on the surface by electromagnetic radiation. Meer weergeven 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 … Meer weergeven When hydrogen gas is accreted onto a white dwarf from a binary companion star, the hydrogen can fuse to form helium for a narrow … Meer weergeven • Carbon detonation Meer weergeven During the red giant phase of stellar evolution in stars with less than 2.0 M☉ the nuclear fusion of hydrogen ceases in the core as it is depleted, leaving a helium-rich core. While fusion of hydrogen continues in the star's shell causing a continuation of the … Meer weergeven Shell helium flashes are a somewhat analogous but much less violent, nonrunaway helium ignition event, taking place in the absence of degenerate matter. They … Meer weergeven Webrange will leave the MS burning helium in their cores (e.g., Gallart et al. 2005, and references therein), becom-ing more luminous and redder in color, and will popu-late the red HeB (RHeB) branch in a CMD. The RHeB stars will traverse the CMD toward bluer colors, mak-ing the “blue loop”, and populate the blue HeB (BHeB) branch.

WebThis was necessary in order to avoid the onset of helium burning. A consequence of this constraint is the existence of a forbidden region in the HR diagram above log (L/L) = -0.25 and hotter than log T eff = 4.45, where helium white dwarfs can exist only for brief intervals. All the models were evolved to log (L/L) = -5.
