The Disruption Time of Clusters in Different Galaxies
If the cluster formation rate is constant and the disruption time of clusters depends only on their initial mass as t dis = t 4 × ( M cl /10 4 M ⊙ ) γ , the values of t 4 and γ can be derived in a very simple way from the age and mass histograms of observed clusters. We derived these values from clu...

and γ can be derived in a very simple way from the age and mass histograms of observed clusters. We derived these values from cluster samples in fields of five galaxies: M51, M33, LMC, SMC and the solar neighbourhood. The values of γ are the same in the five galaxies with < γ > = 0.62 ± 0.03. However the disruption time
