Abstract

Using data from the literature, we made a list of individual estimates of the solar Galactocentric distance, which were performed after 2017 by different methods. These values have not yet been used to calculate the best value of mean \({{R}_{0}}\). For the sample containing 21 estimates, based on the standard approach, we found the weighted mean \({{\bar {R}}_{0}} = 8.14\) kpc with the dispersion \(\sigma = 0.16\) kpc, and using the median statistics, we obtained the estimate \({{R}_{0}} = 8.15 \pm 0.11\) kpc. For practical use, the value \({{R}_{0}} = 8.1 \pm 0.1\) kpc can be recommended.

太阳半乳心距离最佳值的新估计

摘要

使用文献中的数据，我们列出了 2017 年后通过不同方法进行的太阳半乳中心距离的个人估计。这些值尚未用于计算均值\({{R}_{0}}\)的最佳值。对于包含 21 个估计值的样本，基于标准方法，我们发现加权均值\({{\bar {R}}_{0}} = 8.14\) kpc 与离散度\(\sigma = 0.16\) kpc ，并使用中位数统计数据，我们获得了估计值\({{R}_{0}} = 8.15 \pm 0.11\) kpc。对于实际使用，可以推荐值\({{R}_{0}} = 8.1 \pm 0.1\) kpc。
