← ScienceWhich outcome results in stellar nucleosynthesis due to higher temperatures?
A)Increased heavy element isotopic abundance✓
B)Decreased hydrogen fusion reaction rate
C)Reduced stellar gravitational equilibrium
D)Enhanced neutron capture cross-sections
💡 Explanation
Increased heavy element isotopic abundance occurs because a higher temperature allows for overcoming the increased Coulomb barrier via quantum tunneling, resulting in fusion reactions, therefore, shifting element composition higher rather than stopping fusion.
