The observational features of blue stragglers (BSs) show great differences among the different stellar systems, such as Galactic halo, open clusters, globular clusters, and dwarf galaxies.

不同恒星系統(tǒng)(銀河系暈、疏散星團、球狀星團、矮星系)中藍離散星所表現(xiàn)出的觀測特性各不相同,這與恒星系統(tǒng)動力學(xué)環(huán)境及相應(yīng)的藍離散星主導(dǎo)形成機制直接相關(guān)。
