Elements heavier than iron originate from supernova nucleosynthesis and neutron star mergers
the verdict
SUPPORTED
the evidence backs this
confidence 90/100
Astrophysical evidence from both gravitational-wave multi-messenger astronomy and nucleosynthesis modeling confirms that elements heavier than iron are forged via rapid neutron-capture (r-process) events occurring during supernova explosions and neutron star mergers.
