摘要
长周期视双星系统A 1913AB， P≈3360 yr (A), A 1710, P≈111 yr (b), COU1394, P≈330 yr (c), BU1185, P≈28 yr (d), A 122, P≈103 yr (e), A 570, P≈30 yr (f)的新轨道。用于计算轨道要素的观测数据用小绿叉或红点表示，后者表示由法国卡伦的瞳孔干涉散斑相机和日冕仪（PISCO）观测得出的新位置。对于每个物体，主分量的位置用一个大叉表示；经过这一点的虚线就是横横线。这项工作对长周期视觉双星系统的持续监测是一个有价值的贡献，这对精炼系统恒星质量是重要的。详见M. Scardia等人的论文，e70000。
New orbits of long period visual binary systems A 1913AB, P ≈ 3360 yr (a), A 1710, P ≈ 111 yr (b), COU1394, P ≈ 330 yr (c), BU1185, P ≈ 28 yr (d), A 122, P ≈ 103 yr (e), and A 570, P ≈ 30 yr (f). The observational data used for the calculation of the orbital elements are plotted as small green crosses or red dots, the latter indicating the new positions derived from observations with the Pupil Interferometry Speckle camera and Coronograph (PISCO) at Calern, France. For each object, the location of the primary component is indicated with a big cross; the dashed straight line going through this point is the apsidal line. This work is a valuable contribution to the continuing monitoring of long period visual binary systems, which is important for refining systemic stellar masses. For details see the paper by M. Scardia et al., e70000.
期刊介绍：
Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
