← ScienceWhich effect initiates fusion within the core of small red dwarf stars?
A)Quantum tunneling of hydrogen nuclei✓
B)Gravitational collapse overcoming electrostatic repulsion
C)Increased convective heat-transfer efficiency
D)Enhanced radiative energy transport capability
💡 Explanation
Fusion starts with tunneling, because hydrogen nuclei must overcome electrostatic repulsion via quantum tunneling. Consequently, fusion happens, rather than repulsion dominating; different reactions occur in larger stars.
