What star with strong gravity allowing the formation of more oxygen and magnesium?

Massive stars, particularly those more than eight times the mass of the Sun, undergo fusion processes that lead to the formation of heavier elements like oxygen and magnesium. During their lifecycle, these stars fuse helium into heavier elements in their cores, and when they evolve into supernovae, they disperse these elements into space. This strong gravitational force allows for intense nuclear reactions, contributing to the synthesis of these elements in the universe. An example of such a star is a red supergiant, which can eventually explode, enriching the surrounding interstellar medium with oxygen and magnesium.
