← ScienceWhich outcome occurs when increased alpha particle production inhibits stellar core hydrogen fusion?
A)Accumulation of helium ash✓
B)Accelerated convective energy transport
C)Increased rate carbon-nitrogen-oxygen cycle
D)Enhanced rate triple-alpha process
💡 Explanation
Inefficient hydrogen fusion leads to helium 'ash' accumulation because the proton-proton chain is slowed; hydrogen nuclei can’t readily fuse. This mechanism causes the increase in helium. Therefore, helium abundance rises rather than triggering other cycles.
