Col 69 星团于 Lambda Orionis 星形成区域的背景

天体物理学 2007-05-23 v1

摘要

Lambda Orionis星形成区域是一个复杂结构,包括Col 69 (Lambda Orionis) 星团和B30 & B35暗云。我们在该星形成区域的中心星团 (Col 69) 收集了深入的光学光度测量和光谱 spectroscopy,并结合2MASS红外数据,以推导该星团的初始质量函数,在质量范围50-0.02 M(sun)内。此外,我们研究了H(alpha)和锂等价宽度,以及光学红外光度,以推导Col 69的年龄 (5±2 Myr),并将这些性质与B30 & B35成员的性质进行比较。
