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). … Web3.55M subscribers.

However, the core temperature will not get hot enough to fuse carbon or oxygen. Instead, it "stiffens", and the star enters a second red giant phase. Eventually, the star's outer layers are gently blown away and form a planetary nebula. WebPlanetary nebulae seem to mark the transition of a medium mass star from red giant to white dwarf. Stars that are comparable in mass to our Sun will become white dwarfs within 75,000 years of blowing off their envelopes. Eventually they, like our Sun, will cool down, radiating heat into space and fading into black lumps of carbon. dame undershirt creative stockings
