The orbital angular momenta of binary galaxies - The dependence on morphological type
Abstract
Mean values of total and specific orbital angular momenta are systematically analyzed for binary galaxies of various types. The angular momenta of the pairs which include an irregular galaxy are considerably smaller than those for pairs of other types. The distribution of orbital angular momenta of the pairs which include an Sb galaxy and the distribution of the pairs which do not include an Sb galaxy are very different. Most pairs which include an Sb galaxy have orbital angular momentum of the order of the spin of our Galaxy.
