Radial velocities of 10 spectroscopic binaries

We present new orbits for ten (single-lined) spectroscopic binaries in seven open clusters: NGC 2489, 2567, 3033, 5822, 6134, 6664 and IC 2488 based on 243 individual radial...基于243次独立径向（原文后续内容未完整给出），本研究公布了7个疏散星团（NGC 2489、NGC 2567、NGC 3033、NGC 5822、NGC 6134、NGC 6664及IC 2488）中10颗单谱线分光双星（single-lined spectroscopic binary）的全新轨道解。
