主带小行星分布的小波分析

Analysing the Main Belt asteroid distributions by wavelets

R. V. Baluev, E. I. Rodionov

摘要:

我们进行统计小波分析的主带小行星,寻求统计上显着的小行星家族。我们的目标是测试新的小波分析算法,并将其结果与更传统的方法,如层次聚类。我们首先考虑几个一维分布的各种物理和轨道参数的小行星。然后,我们考虑三个二元分布的三个轨道参数(a,e,i)成对。该空间的完整3D分析在这里不可用,但基于2D结果,我们对重叠的2D家族进行了分解,并得出了总共44个具有确认统计学显著性的3D家族。

英文摘要:

We perform statistical wavelet analysis of the Main Belt asteroids, seeking statistically significant asteroid families. The goal is to test the new wavelet analysis algorithm and to compare its results with more traditional methods like the hierarchic clustering. We first consider several 1D distributions for various physical and orbital parameters of asteroids. Then we consider three bivariate distributions for the three orbital parameters (a,e,i) taken pairwisely. The full 3D analysis of this space is not available here, but based on the 2D results we perform a disentangling of overlapped 2D families and derive total of 44 3D families with confirmed statistical significance.
