摘要

天体信息学领域通过实施先进的数据挖掘程序,为天文发现提供了令人兴奋的新视角。数据洪流改变了各个科学学科的研究实践和方法,包括日常的天文研究。必须使用创新的算法和方法来处理天文数据及其多样性。本研究使用描述性数据挖掘来阐明获取三个双星表之间共同数据的重要性和有效性。这些目录分别是《第九光谱双星轨道目录》(SB9)、《第六目视双星轨道目录》(6COVBS)和《第四干涉测量双星目录》(4CIMBS)。我们收集了2021年最新版第九星表的零散数据,其中包含了大约4021个双星系统的天文信息。然后,我们在6COVBS中搜索这些双星系统的轨道,以高精度地计算它们的物理和轨道性质。在那之后,我们使用4CIMBS在其最新的2020年版本中,在66225颗已分辨的恒星中寻找这些恒星的新观测结果,以计算新的轨道。通过这项研究,我们在这些星表中发现了大约600个标准系统,这些系统为从单个质量开始,通过光谱轨道解与视觉轨道解的结合,计算这类双星的许多物理性质提供了宝贵的数据。此外,通过与“盖亚”和“依巴谷”等卫星的轨道视差进行高精度计算,为验证卫星数据的有效性提供了一种新的、必要的方法。

Astroinformatics: The Importance of Mining Astronomical Data in Binary Stars Catalogues
The field of Astroinformatics offers exciting new perspectives on astronomical discovery through the implementation of advanced data mining procedures. Data deluges transform research practices and methodologies across various scientific disciplines, including day-to-day astronomical research. It is essential to use innovative algorithms and methods to process astronomical data and its variety. Descriptive Data Mining was used in this study to clarify the importance and effectiveness of obtaining common data between three binary star catalogs. These catalogues are The Ninth Catalogue of Spectroscopic Binary Orbits (SB9), The Sixth Catalog of Orbits of Visual Binary Stars (6COVBS), and The Fourth Catalog of Interferometry Measurements of Binary Stars (4CIMBS). We collect scattered data from the Ninth Catalog in its latest edition in 2021, which contains astronomical information for approximately 4021 binary systems. Then we search for the orbits of these binary systems in the 6COVBS to calculate the physical and the orbital properties with high accuracy. After that, we use the 4CIMBS to look for new observations of these stars in 66,225 resolved stars in its latest edition 2020 to calculate new orbits. As a result of this research, we have found about 600 standard systems among these catalogues, which are valuable data to calculate many physical properties of such binary stars, starting from individual masses, by the combination of the spectroscopic orbital solution with the visual orbital solutions. Furthermore, calculate the orbital parallax for each system with high accuracy compared with those from space missions such as Gaia and Hipparcos give us a new and essential method to verify the validity of the data from those satellites.
