Abstract in brief

  • The study used JWST observations to analyze the supernova associated with the very bright gamma-ray burst GRB 221009A, finding no signs of r-process element production, which are typically associated with heavy element formation.
  • The supernova closely resembled SN 1998bw in brightness and behavior, indicating that the explosion mechanism is independent of the gamma-ray burst, and highly energetic GRBs are unlikely sources of r-process elements.
  • The host galaxy of GRB 221009A has low metallicity and active star formation, suggesting environmental factors might influence the extreme energy of this burst, but it does not necessarily connect to heavy element synthesis through r-process nucleosynthesis.
