Stellar association — 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 stars. The stars share a common origin, but have become gravitationally… … Wikipedia
Open cluster family — In astronomy, an open cluster family is a group of approximately coeval (age range ∼30 Myr) young open star clusters located in a relatively small region of the Galactic disk (radius ∼250 pc). Introduction Open star clusters do not form in… … Wikipedia
Stellar evolution — Life cycle of a Sun like star Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most… … Wikipedia
