Solar Structure: Structures & Vocabulary

The Sun is a self-gravitating sphere of hot plasma organized into layers defined by how energy is generated, transported, and emitted. Understanding solar structure explains where fusion occurs, why granulation appears on the photosphere, how energy reaches space, and why different solar-atmosphere layers dominate different wavelengths.

supported

Gravity compresses the solar interior while gas and radiation pressure resist collapse, producing hydrostatic equilibrium.

supported

Solar models are constrained by the Sun's mass, radius, luminosity, composition, spectrum, and age.
