摘要

发现小天体当晚收集的数据集构成过短弧线(TSA),导致差分校正程序失败。这使得有必要在随后的夜晚恢复该物体,以收集更多的观测数据,从而计算出初步的轨道。在这项工作中,我们提出了一种基于约束Delaunay三角剖分采样允许区域(AdRe)的恢复技术。我们使用对数和指数度量,对以下近地小行星(3122)Florence, (3200) Phaethon, 2003 GW,(1864)代达罗斯,2003 BH84和1977 QQ5)构建了地心和地心变量的AdRe;和主带小行星:(1738)Oosterhoff, (4690) Strasbourg, (555) Norma, 2006 SO375, 2003 GE55和(32811)Apisaon。利用采样技术,我们建立了这些天体的星历区,观测间隔从25分钟到2小时不等,传播时间从1天到47天不等。除了(3122)佛罗伦萨和(3200)法厄同外,所有这些物体都是在95 ' × 72 '的视野范围内可恢复的,因为它们是在最接近地球的时候观察到的。在2006 SO375的案例中,我们进行了一次额外的测试,只进行了两次相隔2分钟的观察,在发现后的28天内实现了恢复,这证明了我们技术的潜力。

Recovery of Asteroids from Observations of Too-Short Arcs by Triangulating Their Admissible Regions
The data set collected during the night of the discovery of a minor body constitutes a too-short arc (TSA), resulting in failure of the differential correction procedure. This makes it necessary to recover the object during subsequent nights to gather more observations that will allow a preliminary orbit to be calculated. In this work, we present a recovery technique based on sampling the admissible region (AdRe) by the constrained Delaunay triangulation. We construct the AdRe in its topocentric and geocentric variants, using logarithmic and exponential metrics, for the following near-Earth-asteroids: (3122) Florence, (3200) Phaethon, 2003 GW, (1864) Daedalus, 2003 BH84 and 1977 QQ5; and the main-belt asteroids: (1738) Oosterhoff, (4690) Strasbourg, (555) Norma, 2006 SO375, 2003 GE55 and (32811) Apisaon. Using our sampling technique, we established the ephemeris region for these objects, using intervals of observation from 25 minutes up to 2 hours, with propagation times from 1 up to 47 days. All these objects were recoverable in a field of vision of 95’ × 72’, except for (3122) Florence and (3200) Phaethon, since they were observed during their closest approach to the Earth. In the case of 2006 SO375, we performed an additional test with only two observations separated by 2 minutes, achieving a recovery of up to 28 days after its discovery, which demonstrates the potential of our technique.

期刊介绍: JASS aims for the promotion of global awareness and understanding of space science and related applications. Unlike other journals that focus either on space science or on space technologies, it intends to bridge the two communities of space science and technologies, by providing opportunities to exchange ideas and viewpoints in a single journal. Topics suitable for publication in JASS include researches in the following fields: space astronomy, solar physics, magnetospheric and ionospheric physics, cosmic ray, space weather, and planetary sciences; space instrumentation, satellite dynamics, geodesy, spacecraft control, and spacecraft navigation. However, the topics covered by JASS are not restricted to those mentioned above as the journal also encourages submission of research results in all other branches related to space science and technologies. Even though JASS was established on the heritage and achievements of the Korean space science community, it is now open to the worldwide community, while maintaining a high standard as a leading international journal. Hence, it solicits papers from the international community with a vision of global collaboration in the fields of space science and technologies.
