最近，De Marchi，Paresce和Pulone研究了20个球状星团的样本，发现所有高浓度的星团都有陡峭的恒星质量函数，而低浓度的星团则有相对较浅的质量函数。没有发现具有平坦质量函数和高浓度的球状星团。这看起来很奇怪，因为更集中的星星团被认为是动态地进化，应该通过蒸发失去更多的低质量恒星，这将导致低质量部分的质量函数较浅。
Recently, De Marchi, Paresce & Pulone studied a sample of 20 globular clusters and found that all clusters with high concentrations have steep stellar mass functions while clusters with low concentration have comparatively shallow mass functions. No globular clusters were found with a flat mass function and high concentration. This seems curious since more concentrated star clusters are believed to be dynamically more evolved and should have lost more low-mass stars via evaporation, which would result in a shallower mass function in the low-mass part.
