Artists visualization of GRB 221009A revealing the narrow relativistic jets– emerging from a main black hole– that gave increase to the GRB and the broadening remains of the original star ejected via the supernova explosion.”When we validated that the GRB was produced by the collapse of a massive star, that gave us the opportunity to evaluate a hypothesis for how some of the heaviest elements in the universe are formed,” stated Northwesterns Peter Blanchard, who led the research study. “We did not see signatures of these heavy elements, recommending that exceptionally energetic GRBs like the B.O.A.T. do not produce these elements.– Peter Blanchard, CIERA Postdoctoral FellowAstrophysicists have actually hypothesized that heavy elements also might be produced by the collapse of a quickly spinning, massive star– the precise type of star that generated the B.O.A.T. Using the infrared spectrum obtained by the JWST, Blanchard studied the inner layers of the supernova, where the heavy elements should be formed.”Reference: “JWST detection of a supernova associated with GRB 221009A without an r-process signature” by Peter K.
