WebApr 11, 2024 · When stars swell up to become red giants, they have very large radii and therefore a low escape velocity. 1 Radiation pressure, stellar pulsations, and violent events like the helium flash can all drive atoms in the outer atmosphere away from the star, and cause it to lose a substantial fraction of its mass into space. Red giants are evolved from main-sequence stars with masses in the range from about 0.3 M☉ to around 8 M☉. When a star initially forms from a collapsing molecular cloud in the interstellar medium, it contains primarily hydrogen and helium, with trace amounts of "metals" (in stellar structure, this simply refers to any element that is not hydrogen or helium i.e. atomic number greater than 2). … customer and stakeholder focus

Red giant helium flash

WebWhen the Sun becomes convective, it rapidly increases in luminosity at nearly constant temperature and becomes a Red Giant reaching a radius 20 % larger than the Earth's current orbit (1 Astronomical Unit). During this phase, strong stellar winds cause the Sun to lose ~ 30 % of its mass. WebApr 9, 2015 · The helium flash occurs at the tip of the first ascent red giant branch in stars with masses between 0.5 and about 2 solar masses. At this point the star consists of a helium core surrounded by a vigorously burning shell of hydrogen, surrounded by a very large convective envelope.
