← ScienceWhich outcome results when a star exhausts its hydrogen fuel at its core during stellar nucleosynthesis?
A)Core contraction raises temperature✓
B)Helium fusion immediately starts
C)Strong forces balance gravity
D)Neutron degeneracy pressure weakens
💡 Explanation
Core contraction causes the temperature to rise due to increased gravitational pressure until helium fusion can commence through the triple-alpha process involving nuclear binding energy; therefore, temperature increases, rather than immediate helium fusion because threshold temperature must occur first.
