Dans le cas où une des deux composantes est beaucoup plus brillante que l'autre, on ne voit pas une décomposition des raies, mais simplement un mouvement de va-et-vient de la longueur d'onde des raies de l'étoile la plus brillante pendant le mouvement orbital. Quand le mouvement des deux composantes est perpendiculaire à la direction d'observation, on n'a pas d'effet Doppler et les raies spectrales sont simples [...]  1, record 1, French, - mouvement%20orbital
