Abstract i discuss stellar spectroscopy and nucleosynthesis astronomers recognize two distinct episodes of nucleosynthesis, primordial (big bang), and stellar. Stellar nucleosynthesis refers to the assembly of the natural abundances of the chemical. Nuclear astrophysics started in the late 1930s, when hans bethe (1939) discussed both the proton-proton chain and the carbon-nitrogen cycle for turning hydrogen into.
Stellar nucleosynthesis creates heavier elements from hydrogen and helium learn how stars use fusion to produce heavier and heavier nuclei. With the formation of stars, heavier nuclei were created from hydrogen and helium by stellar nucleosynthesis , a process that continues today. Following stellar nucleosynthesis the calculation of stellar nucleosynthesis requires the simultaneous solution for a set of coupled ﬀtial equations, each of which has.
