EDMOND数据库中流星雨的独立识别

Independent identification of meteor showers in EDMOND database

R. Rudawska, P. Matlovič, J. Tóth, L. Kornoš

摘要:

国家网络和国际流星组织视频流星数据库之间的合作和数据共享产生了欧洲视频流星网络数据库。数据库的当前版本(EDMOND 5.0)包含从2001年到2014年收集的144 751个轨道。在我们的调查中,我们使用EDMOND数据库,以确定现有的和新的流星雨在数据库中。在调查的第一步中,使用Dsh标准,我们发现每个流星周围的相似性阈值内的组。使用基于地心参数(太阳经度、赤经、赤经和地心速度)的新函数计算和比较各组的平均参数。类似的组被合并成最后的集群(代表流星雨),并与IAU流星数据中心的流星雨列表进行比较。本文介绍了所提出的方法获得的结果。

英文摘要:

Cooperation and data sharing among national networks and International Meteor Organization Video Meteor Database (IMO VMDB) resulted in European viDeo MeteOr Network Database (EDMOND). The current version of the database (EDMOND 5.0) contains 144 751 orbits collected from 2001 to 2014. In our survey we used EDMOND database in order to identify existing and new meteor showers in the database. In the first step of the survey, using Dsh criterion we found groups around each meteor within similarity threshold. Mean parameters of the groups were calculated and compared using a new function based on geocentric parameters (solar longitude, right ascension, declination, and geocentric velocity). Similar groups were merged into final clusters (representing meteor showers), and compared with IAU Meteor Data Center list of meteor showers. This paper presents the results obtained by the proposed methodology.
