Helium-Burning Phase

The helium-burning phase marks a critical stage in the life cycle of massive stars, characterized by the fusion of helium nuclei into heavier elements like carbon and oxygen. This phase follows the hydrogen-burning phase and precedes subsequent stages leading to the star's eventual fate. It signifies a transition where the star's core contracts, increasing temperature and pressure to sustain helium fusion reactions. Understanding the dynamics of this phase is fundamental in unraveling the evolution of stars, shaping our comprehension of stellar processes, and offering insights into the synthesis of elements crucial for the cosmos' chemical enrichment.
