En astrophysique, le mécanisme de Kelvin-Helmholtz est un phénomène qui a lieu lorsque la surface d'une étoile ou d'une planète se refroidit. Ce refroidissement entraîne une baisse de pression et le corps céleste la compense en se contractant. Cette compression entraîne alors un réchauffement du centre du corps.

WebbDefinition of the Photosphere. As we look down into the atmosphere at the surface of the Sun the view becomes more and more opaque. The point where it appears to become completely opaque is called the photosphere. Thus, the photosphere may be thought of as the imaginary surface from which the solar light that we see appears to be emitted.
