太阳邻域中的运动群候选星表

A Catalog of Moving Group Candidates in The Solar Neighborhood

Jingkun Zhao, Gang Zhao, Yuqin Chen

摘要:

基于核估计和小波技术,我们已经确定了22个运动群候选人在太阳附近的样本,其中包括约14,000矮星和6000巨星。其中六个星系团以前被称为武仙座星系团、锡鲁斯-乌玛星系团、毕宿星星系团、卡斯特星系团、昂宿星星系团和IC 2391;其中五个星系团也被其他作者报道过。11个运动群候选者在矮星或巨星样品中显示出突出的结构,这是以前文献中没有报道的。

英文摘要:

Based on the kernel estimator and wavelet technique, we have identified 22 moving group candidates in the solar neighborhood from a sample which includes around 14,000 dwarfs and 6000 giants. Six of them were previously known as the Hercules stream, the Sirus-UMa stream, the Hyades stream, the Caster group, the Pleiades stream, and the IC 2391; five of them have also been reported by other authors. 11 moving group candidates, not previously reported in the literature, showprominent structures in dwarf or giant samples.Acatalog of moving group candidates in the solar neighborhood is presented in this work.
