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 ...

Although the periodic table is filled with elements, nuclear fusion at the center of stars can only produce elements with atomic masses lower than iron—after than, neutron captures processes known as ...

Heavy duty A high-energy photonic jet (white and blue) blasts through a collapsing star with a black hole at its centre. The cocoon where free neutrons may be available for the r-process is shown in ...
