Structure of a Massive Star in Late Evolutionary Stages | Stellar Interior Diagram #3730232 (License: Personal Use)

The diagram depicts a massive star (≥8 M☉) in its final evolutionary phase, featuring concentric layers where different nuclear fusion reactions occur: hydrogen burns in the outermost shell, helium in the next, and carbon/oxygen in the core. Arrows indicate convection in the outer envelope and radiative energy transport inward, highlighting how energy flows from the core outward through distinct zones.

Used in astronomy education, astrophysics textbooks, and科普 articles explaining stellar evolution and supernova progenitors; targets students, educators, and space enthusiasts seeking visual understanding of pre-supernova star structure.
