论文摘要
等级恒星系统中的时期，偏心和质量告诉我们这些迷人物体的形成和早期演变。为了补充附近太阳能恒星的多重性统计，根据高分辨率在数年期间收集的高分辨率echelle Spectra，确定了15个层次结构内部子系统的19个新光谱轨道。尽管该系列的先前论文主要包含短期轨道，但大多数时期都按照一年的命令。这些层次结构的主要组成部分是HIP 7852，9148，12548，21079，24320，27970，34212，56282，56282，57860，76400，76816，76816，81394，81394，96284，96284，100420，100420，100420 and HD 108938。具有低质量光谱辅助的2+2个体系结构），髋关节56282（行星型3+1个层次结构）和嘻哈27970（一个紧凑的三重，周期为15和1049天）。
Periods, eccentricities, and masses in hierarchical stellar systems inform us on the formation and early evolution of these fascinating objects. To complement the multiplicity statistics of nearby solar-type stars, 19 new spectroscopic orbits of inner subsystems in 15 hierarchies (10 triples and 5 quadruples) are determined based on high-resolution echelle spectra collected during several years. While previous papers of this series contained mostly short-period orbits, here most periods are on the order of a year. The main components of these hierarchies are HIP 7852, 9148, 12548, 21079, 24320, 27970, 34212, 56282, 57860, 76400, 76816, 81394, 96284, 100420, and HD 108938. Noteworthy systems are HIP 12548 and 24230 (hierarchies of 2+2 architecture with low-mass spectroscopic secondaries), HIP 56282 (a planetary-type 3+1 hierarchy), and HIP 27970 (a compact triple with periods of 15 and 1049 days).
