In a study published in The Astrophysical Journal, scientists have proposed the features of rapid neutron capture process (r-process) nucleosynthesis in a novel scenario, common envelope jet ...

You can't have gold until a nucleus decays. The specifics of that process have been hard to pin down, but UT's nuclear physicists have published three discoveries in one paper explaining key details.

Heavy duty: artist’s impression of a kilonova releasing r-process elements into the cosmos. (Courtesy: ESO/L Calçada/M Kornmesser) The mystery of where heavy elements such as gold and silver come from ...

Hydrogen and helium formed shortly after the Big Bang. Stars create elements lighter than iron through nuclear fusion. Supernovae produce elements heavier than iron via the r-process. Neutron star ...

Elements heavier than iron, such as gold and uranium, are primarily formed through neutron capture processes, specifically the rapid neutron capture process (r-process). The r-process, unlike the ...
