Roche-lobe

WebUn lobe de Roche est une surface équipotentielle de Roche. Elle est tracée dans un repère tournant lié à deux corps célestes orbitant à vitesse constante sur des trajectoires circulaires. Le potentiel de Roche tient compte à la fois de la force de gravitation et de la force centrifuge. Par extension, l'équipotentielle particulière ...
