Supergranules

Definition

Supergranules are large-scale convection cells on the surface of the Sun that are several times the size of granules. They play a crucial role in the transport of energy and material within the Sun's interior, which is directly relevant to the topics of thermal and gravitational energy sources as well as the solar interior theory.

1. Supergranules are typically 20,000 to 30,000 kilometers in diameter, making them much larger than the smaller granules on the Sun's surface.
2. The formation of supergranules is driven by convection in the Sun's outer layers, where hot plasma rises and cooler plasma sinks, creating a pattern of large-scale circulation.
3. Supergranules play a crucial role in the transport of energy and material within the Sun's interior, as they help to distribute the heat generated in the core throughout the outer layers.
4. The study of supergranules and their behavior provides important insights into the dynamics of the Sun's interior, which is a key focus of the theory of the solar interior.
5. Observations of the Sun's surface, including the patterns of supergranules, are used to infer the structure and composition of the Sun's interior, which is essential for understanding the sources of the Sun's thermal and gravitational energy.
