Web2 de abr. de 2024 · First post here so hi all. My question (s) is regarding the formation of solar masses by accretion of gases and dust. From what I understand, stars are formed by large clouds of gasses and dust particles pulling together and with enough gravity, (magnetic fields), and time. A fusion process begins. Afterwards, planetary bodies, dwarf planets ... WebIn all the discussions about how the heavy elements in the universe are forged in the guts of stars and especially during a star's death, I usually hear that once the star begins fusing lighter atoms to produce iron (Fe) that's the end of the star's life and the whole system collapses onto itself; and based on how massive the star was initially, it has different …
WebElemental Abundances. Most of the atoms in the universe are either hydrogen or helium, formed within the first few minutes after the Big Bang.
