稀释形成球状星团中第二代星的物质：未演化恒星的贡献
Diluting the material forming the second generation stars in Globular Clusters: the contribution by unevolved stars
摘要：
在这篇简短的通讯中，我们考虑了这样一种可能性，即演化程度低于污染源的恒星是解释第二代球状星团（GC）恒星的观测组成以及Na-O和Mg-Al关系所需的稀释源。如果这些恒星在相关的历元中损失了0.5-1%的质量，就有足够的稀释物质来产生观测到的质量关系。在这种情况下，原始GC的质量是GC当前质量的几十倍。虽然严格来说并非不可能，但这是一个需要更多支持的严格假设。如果这一假设成立，那么GC中的原始（第一代）种群与实地种群之间的联系将非常强。
英文摘要：
In this short communication we consider the possibility that stars less evolved than the polluters are the source of the dilution needed to explain the observed composition of second-generation globular cluster (GC) stars and the Na-O and Mg-Al anticorrelations. If these stars can lose 0.5-1% of their mass during the relevant epochs, there is enough diluting material to produce the observed anticorrelations. In this case, the original mass of proto-GCs was several tens times higher than the current mass of GCs. While not strictly impossible, this is a stringent hypothesis that needs more support. Should this scenario be found true, then the link between the primordial (first-generation) population in GC and the field population would be very strong.
