Here we propose, for the first time, that rapid removal of stars from the outer parts of a cluster by the strong tidal field in the inner region of our Galaxy can unveil its BH sub-cluster, which appears as a star cluster that is gravitationally bound by an invisible mass. We study the formation and properties of such systems through direct N-body computations and estimate that they can be present in significant numbers in the inner region of the Milky Way. We call such objects "dark star clusters"
Не, не читали они Стругацких, у тех уже были "звездные кладбища"...
P.S. И вообще это все фигня - скопления перестанет быть гравитационно-связанным значительно раньше, чем из него уйдут все звезды. Теоретики...
