对恒星在几个老盘群聚体和几个晕群聚体中的HR图分布的研究表明，蓝散射现象是普遍存在的。在所有考虑的情况下，发现有几颗恒星远离由半经验等时线所定义的轨道，该等时线最符合聚集体中大部分恒星的分布。结果支持年轻盘聚集体中蓝散射的星暴解释。参考文献162篇。
A study of the distribution in the HR diagram of stars in several old-disk population aggregates and in several halo-population aggregates indicates that the blue straggler phenomenon is ubiquitous. In all the cases considered, several stars are found to lie far from the locus defined by a semiempirical isochrone that best fits the distribution of the bulk of the stars in the aggregate. The results support the starburst interpretation of blue stragglers in young-disk aggregates. 162 references.
