SUMMARY

The main sources of element formation in the universe include various nucleosynthesis processes. Silicon and nickel are primarily produced through fusion in the cores of high-mass stars, while lithium originates from primordial nucleosynthesis. Bismuth results from slow neutron capture in high-mass stars, and uranium is formed via rapid neutron capture during supernova events. This discussion clarifies the specific processes responsible for the creation of these elements in stellar environments.

PREREQUISITES
  • Understanding of stellar nucleosynthesis
  • Knowledge of high-mass and low-mass star characteristics
  • Familiarity with neutron capture processes
  • Basic principles of astrophysics
NEXT STEPS
  • Research the process of stellar nucleosynthesis in high-mass stars
  • Study the mechanisms of rapid and slow neutron capture
  • Explore the role of supernovae in element formation
  • Investigate primordial nucleosynthesis and its significance in the early universe
USEFUL FOR

Astronomy students, astrophysicists, and anyone interested in the processes of element formation in stars and the origins of the universe's chemical composition.

By choosing among the following five options, what is the main source in the universe for the origin of the elements : silicon, lithium, bismuth, nickel and uranium?

Primordial nucleosynthesis – fusion in core of low-mass stars – fusion in core of high-mass stars – slow neutron capture in high mass-stars - rapid neutron capture in supernovae.

Thanks

Sorry, next time I will choose the right forum.
The following is what I think is the right answer but I'd like to be confirmed.

silicon = Fusion in core of low-mass star
lithium = Primordial nucleosynthesis
bismuth = Low neutron capture in high mass-stars
nickel = Fusion in core of low-mass star
uranium = Rapid neutron capture in supernovae

Thanks!
 
For nickel I think you mean fusion in the core of a HIGH mass star. Also, isn't silicon one of the last elements produced in high mass stars and not low mass stars? I'm not formally educated in astrophysics so I could be wrong.
