    A stellar association is a very loose star cluster, looser than both open clusters and globular clusters. Stellar associations will normally contain from 10 to 100 or more visible stars. An association is primarily identified by commonalities in its member stars' movement vectors, ages, and chemical compositions.

    A stellar association is a very loose star cluster, looser than an open cluster. A moving group is the remnant of such a stellar association. Members of stellar associations and moving groups share similar kinematic properties, as well as similar ages and chemical composition.

    Stellar association, a very large, loose grouping of stars that are of similar spectral type and relatively recent origin. Stellar associations are thought to be the birthplaces of most stars.

    A stellar association is a loose group of stars that are moving in the same direction but are not gravitationally bound to each other. The most highly visible type of stellar association is dominated by young, massive stars and is called an OB association.

    A stellar association is a loose star cluster, looser than both open clusters and globular clusters. Stellar associations usually have from 10 to 100 or more stars. The stars have a common origin.

    The T associations (short for T Tauri associations) are formed by groups of T Tauri stars associated with the clouds of interstellar matter (nebulas) in which they occur. About three dozen are recognized. A T Tauri star is characterized by irregular variations of light, low luminosity, and hydrogen line (H-alpha) emission.
