论文摘要
贝德尔等。 (2018年)给出了79个主要是G-warf明星的精确差分丰度。我们以类似于这些作者使用的方式校正了银河化学演化的这些丰度,但具有从线性拟合到[El/h]与年龄相对于[El/fe]的图的参数。我们使用Lodders(2003)和Wood等人的值来研究与50%冷凝温度相关的所得丰度。 (2019),并与Bedell等人的结果进行比较。 HD 196390在具有79星样本的最显着相关性方面是不同的。我们报告了具有较低意义但感兴趣的恒星子集的统计数据。
Bedell et al. (2018) give precision differential abundances for 79 mostly G-dwarf stars. We correct these abundances for Galactic chemical evolution in a manner similar to that used by these authors but with parameters derived from linear fits to plots of [El/H] vs. age in lieu of [El/Fe]. We examine the resulting abundances for correlations with the 50% condensation temperature using values from both Lodders (2003) and Wood et al. (2019), and compare with the results of Bedell et al. HD 196390 is distinct in having the most significant correlation of the 79-star sample. We report statistics for a subset of stars with lower significance, but of some interest.
