Star-Forged Periodic Elements
List of the periodic elements and which stellar events forged which of the elements. We are literally made of star stuff.
BB = Big Bang fusion
CR = cosmic ray spallation
ND = nuclear decay
NS = neutron star merger
PA = particle accelerator (manmade)
PN = planetary nebula (red giant death)
SNIa = Type Ia supernova (white dwarf explosion)
SNII = Type II supernova (high-mass star core collapse)
