gravity darkening coefficient hamgar-e târikeš-e gerâneši Fr.: coefficient de l'assombrissement gravitationnel According to the → von Zeipel theorem, the emergent flux, F, of total radiation at any point over the surface of a rotationally or tidally distorted star in → hydrostatic equilibrium varies proportionally to the local gravity acceleration: F ∝ geffα, where geff is the → effective gravity and α is the gravity darkening coefficient. See also the → gravity darkening exponent. → gravity; → darkening; → coefficient. |
