Abstract

We have provided an independent analysis of HD and H₂ absorption lines in several systems in our Galaxy using FUSE space telescope archival data and neutral carbon and metal lines in these systems using HST archival data. The obtained HD column densities lie in the range from ∼10¹⁴ to ∼10¹⁶ cm^–2. The obtained column densities were used to estimate physical conditions in the analyzed systems, including cosmic ray ionization rate, which were obtained in the range from ζ ∼ 10^–17 to ∼10^−15.5 s^–1.

银河中的高清分子

我们利用 FUSE 空间望远镜的档案数据对银河系中几个系统的 HD 和 H2 吸收线进行了独立分析，并利用 HST 档案数据对这些系统中的中性碳线和金属线进行了分析。获得的 HD 柱密度范围在 ∼1014 到 ∼1016 cm-2 之间。所获得的柱密度被用来估计所分析系统的物理条件，包括宇宙射线电离率，其范围为ζ ∼ 10-17 ∼10-15.5 s-1。

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
