متن کاملnucleosynthesis with full s - process calculations
We present montage, a post-processing nucleosynthesis code that combines a traditional network for isotopes lighter than calcium with a rapid algorithm for calculating the s-process nucleosynthesis of the heavier isotopes. The separation of those parts of the network where only neutron-capture and beta-decay reactions are significant provides a substantial advantage in computational efficiency....
متن کاملInterstellar 36 S : a probe of s - process nucleosynthesis ⋆
The first detection of a 36 S-bearing molecule in interstellar space is reported. The J=2−1 and 3−2 transitions of C 36 S have been observed toward eight Galactic molecular hot cores. From a comparison with other optically thin isotopic species of CS, the abundance ratio of 34 S/ 36 S is 115(±17). This is smaller than the solar system ratio of 200 and supports the idea that 36 S is, unlike the ...
متن کاملA New Study of s-Process Nucleosynthesis in Massive Stars
We present a comprehensive study of s-process nucleosynthesis in 15, 20, 25, and 30 M stellar models having solar-like initial composition. The stars are evolved up to ignition of central neon with a 659 species network coupled to the stellar models. In this way, the initial composition from one burning phase to another is consistently determined, especially with respect to neutron capture reac...
متن کاملASTROPHYSICAL NEUTRON CAPTURE RATES IN s– AND r–PROCESS NUCLEOSYNTHESIS
Astrophysical neutron capture rates of light and heavy nuclei have been measured and calculated. For the measurements the activation technique was applied at the 3.75 MV Karlsruhe Van de Graaff accelerator, and at the Geel electron linear accelerator (GELINA) the time–of–flight (TOF) method was used. The calculations were performed using direct and compound nuclear capture models.
