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

Using the Gran Telescopio Canarias (GTC), astronomers from the Chinese Academy of Sciences (CAS) and elsewhere have discovered a new extremely r-process-enhanced star in the Milky Way's thin disk. The ...

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 ...

For the first time, astronomers have definitively ID’d a specific heavy element forged by a neutron star merger. Theories of physics have long predicted that about half of the universe’s heavy ...
