论文摘要
审查了跨性别二进制文件的发现和特征。自从第一次发现以来的20年中,出现了大量细节,包括不同人群中的二进制文件的频率,它们的相对大小和分离以及颜色。在全球范围内,这些特性为发现这些二进制文件的种群的起源和演变提供了强大的线索。在过去的十年中,已经确定了越来越多的二进制轨道,这些轨道产生了有关其质量和密度的新信息,以及它们的轨道细节,包括倾斜度,偏心率和相互事件的时机。在2018年,对跨性二进制文件的研究仍然是理解海王星以外的太阳系的最活跃的进步领域之一。
The discovery and characteristics of transneptunian binaries are reviewed. In the 20 years since their first discovery, a wealth of detail has emerged including the frequency of binaries in different populations, their relative sizes and separations, and colors. Taken globally, these properties give strong clues to the origin and evolution of the populations where these binaries are found. In the last ten years and increasing number of binary orbits have been determined which yields a new trove of information on their masses and densities as well as details of their orbits including inclination, eccentricity and the timing of mutual events. In 2018, the study of transneptunian binaries remains one of the most active areas of progress in understanding the Solar System beyond Neptune.
