Convection zone

A thick outer spherical shell of a star shown in cross-section or cutaway as a curved band, colored in warm orange, yellow-orange, and red tones. The layer is filled with many adjacent rounded convection cells arranged side by side, depicted as repeating looping or scalloped overturning patterns with curved circulating arrows, rounded rising plumes, and descending cooler lanes. Darker outlines or mottled boundaries between neighboring cells emphasize the turbulent, boiling texture of churning plasma within the stellar convection zone. Use clean medium linework, a warm flat color palette with subtle soft shading, and simplified scientific-diagram detail.
