New Gold Source? Scientists Find Clues in Magnetar Flares
Scientists have found new evidence that gold, a precious metal, may be created in a different way than previously thought.
They observed a powerful burst of energy from a magnetar, a type of neutron star with an incredibly strong magnetic field.
After the burst, the magnetar emitted gamma rays, which provided hints of the r-process, a process that creates heavy elements like gold.
This discovery suggests that magnetars might also produce gold, adding to the known source of gold created by colliding neutron stars.
This helps scientists understand how elements formed in the universe and the evolution of galaxies and stars.
Researchers found new evidence that magnetar flares may produce gold through the r-process.
The study observed a magnetar emitting strong gamma rays after a flare, providing clues about element creation.
The delayed emission suggested radioactive decay from r-process nuclei.
The team estimated 1.9 septillion kg of r-process material was ejected during the event.
This finding challenges the long-held belief that neutron star mergers were the primary source of gold.
