Massive young star clusters can form new stellar populations from accreted gas

【摘要】：正Stars in star clusters are thought to form in a single burst from a common progenitor cloud of molecular gas.The nature of the resulting"simple stellar populations"has been confirmed in most young massive clusters in the local Universe and also in Milky Way open clusters.However,old,massive"globular"clusters~with ages
