How these connect

Rapid neutron capture (the r-process) and what it relates to. Every line is an evidence-backed relation, and the arrangement is fixed — this address draws this picture, today and next year.

  1. A neutron-star merger is detected in gravitational waves and light · evidence_for · Rapid neutron capture (the r-process)

    The reddening light curve of AT2017gfo matched r-process predictions, establishing neutron-star mergers as a production site.

  2. Kilonova · depends_on · Rapid neutron capture (the r-process)

    A kilonova is powered by the radioactive decay of r-process nuclei made in the merger ejecta; without that synthesis there is no transient to see.

  3. Rapid neutron capture (the r-process) · part_of · Stellar nucleosynthesis

    Rapid neutron capture is one of the processes B2FH identified, and the only route to roughly half the elements heavier than iron.
