  1. Supernova nucleosynthesis - Wikipedia

    In 1946, Fred Hoyle proposed that elements heavier than hydrogen and helium would be produced by nucleosynthesis in the cores of massive stars. [6] It had previously been thought that the elements …

  2. Elemental Abundances - Harvard–Smithsonian Center for Astrophysics

    Most of the atoms in the universe are either hydrogen or helium, formed within the first few minutes after the Big Bang. The other elements are mostly made by nuclear fusion in stars, especially fusion …

  3. Populating the periodic table: Nucleosynthesis of the elements

    Feb 1, 2019 · Elements heavier than helium are produced in the lives and deaths of stars. This Review discusses when and how the process of nucleosynthesis made elements. High-mass stars fuse …

  4. Supernova nucleosynthesis - Wikiwand

    During hydrostatic burning these fuels synthesize overwhelmingly the alpha nuclides (A = 2Z), nuclei composed of integer numbers of helium-4 nuclei. Initially, two helium-4 nuclei fuse into a single …

  5. Background: Dispersion of Elements - Imagine the Universe!

    Mar 8, 2017 · The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The heaviest elements, like iron, …

  6. Nucleosynthesis – How Elements Are Made

    Jun 22, 2022 · Stars fuse hydrogen and helium into heavier nuclei. All stars produce carbon via the triple-alpha process. Carbon releases neutrons, which feed the slow neutron-capture or s-process. …

  7. Lecture 18: Supernovae - Ohio State University

    Supernova explosions are responsible for creating nearly all of the heavy elements seen in nature, with a few important exceptions. The universe starts out with only Hydrogen (75%), Helium (~25%), and a …

  8. Stellar Nucleosynthesis | Core Process, Elements & Stars

    May 28, 2024 · During these colossal explosions, conditions become favorable for the rapid neutron capture process (r-process), which is responsible for creating approximately half of the elements …

  9. The creation of chemical elements by stars | Astronoo

    During supernova explosions, where a large number of neutrons are released in a short period, nuclei rapidly capture neutrons and transform into even heavier elements like gold and lead, thus enriching …

  10. Supernovae - The life cycle of a star - AQA - BBC

    Elements that are heavier than hydrogen and helium are formed. Elements heavier than iron are formed in the supernova explosions of high mass stars.
