  1. Supernova nucleosynthesis - Wikipedia

    The result is a white dwarf which exceeds its Chandrasekhar limit and explodes as a type Ia supernova, synthesizing about a solar mass of radioactive 56 Ni isotopes, together with smaller amounts of other …

  2. 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, …

  3. Nucleosynthesis – How Elements Are Made

    Jun 22, 2022 · Supernova nucleosynthesis: A supernova produces many intermediate-mass elements between oxygen and rubidium. Largely, this involves rapid neutron-capture, although rapid proton …

  4. The Elementary Nature of Cassiopeia A - Smithsonian Institution

    Oxygen is the most abundant element in the human body (about 65% by mass), calcium helps form and maintain healthy bones and teeth, and iron is a vital part of red blood cells that carry oxygen through …

  5. Supernova nucleosynthesis explained

    During supernova nucleosynthesis, the r -process creates very neutron-rich heavy isotopes, which decay after the event to the first stable isotope, thereby creating the neutron-rich stable isotopes of …

  6. Supernova explosions - Las Cumbres Observatory

    At the critical mass, a thermonuclear runaway reaction fuses most of the material to radioactive nickel in a matter of seconds, which then decays to iron. The remaining material is burned into lighter …

  7. supernova - Cosmic Evolution Project - Cal Poly, San Luis Obispo

    Oxygen burning synthesizes silicon, phosphorus, sulfur, and magnesium. The three most common processes are shown here with their relative rates in percent. As a bonus, these reactions produce …

  8. Astr - Chapter 21a & 21b Flashcards | Quizlet

    Which type of heavy atomic nuclei are most common, and why? Even numbered elements, for helium is "giant food" for everything beyond itself.

  9. Radioactive elements formed in the blast (principally Ni and Co) begin to decay, and the energy release heats the surrounding debris. This produces a “bump” in the light-curve, where the decay in …

  10. Supernova - Wikipedia

    Supernova SN 1994D (bright spot on the lower left), a Type Ia supernova within its host galaxy, NGC 4526 A supernova (pl.: supernovae) is a powerful and luminous explosion of a star. A supernova …
