摘要: N-body calculations have shown that hard binaries play a dominant role in the evolution of small stellar systems. However, only one or two such form by dynamical interactions and since final components tend to be massive, their effect observability open clusters are limited relatively short time-scales. In present investigation we consider an initial population with physical times exceeding cluster age. These may applicable later phase when heavier stars suffered mass loss.
