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.

WebbThe Photosphere is around 500 km thick, and this is the layer where most of the Sun’s radiation and rays finally escape, and this is also where sunspots happen. Above the Photosphere is the Chromosphere, which literally can be translated into “sphere of color”, that we can observe during the total solar eclipse. Webb21 mars 2024 · This region of the Sun is the first part of the Sun that is visible to us and we call it the photosphere. This is where the light we see from the Sun originates.

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.

WebbPhotosphere - the visible surface layer where most of the Sun's light is emitted. Sunspots and solar flares can occur here. Chromosphere - a thin layer just above the photosphere that emits mostly ultraviolet light. It contains spicules and prominences that can be seen during a solar eclipse. The photosphere is the lowest layer of the sun's atmosphere — the innermost layer we can observe directly. The term photosphere means "sphere of light" and is the layer where most of the sun's energy is emitted. It takes about eight minutes for sunlight from the photosphere to reach Earth.
