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.
