Collapsing Stars May Dissolve into Neutrons, Forming Heavy Elements: New Study
A recent study proposes that high-energy photons from collapsing stars dissolve the outer layers into free neutrons, leading to the rapid neutron-capture process (r-process) and the creation of heavy elements. This phenomenon, occurring in collapsars, may also explain kilonovae associated with long-duration gamma-ray bursts and addresses questions regarding neutron transport and rare event observations.

Collapsing Stars May Dissolve into Neutrons, Forming Heavy Elements: New Study
A recent study proposes a novel mechanism for the creation of heavy elements like uranium and plutonium. It suggests that as massive stars collapse into black holes, high-energy photons produced in the resulting jets can dissolve the star's outer layers into free neutrons. These neutrons then participate in the rapid neutron-capture process (r-process), forging heavy elements that are expelled into space.
