WebThe S-process (slow neutron capture) occurs in the He burning region (state of a red giant). The R-process ( rapid neutron capture) occurs during the super nova explosion, either within a short distance of the forming neutron star or in the shell where He burning took place prior to the blast when the shock wave hits this area. WebBoth red giants and red supergiants decrease in surface temperature down to around 3500 Kelvin. This is due to the ... Interestingly, the Helium burning shells in the star can begin synthesizing heavier elements due to neutron capture and beta decay to produce elements as ... Neutron stars do emit radiation and heat and over time will slow down.
