"Analysis of young nearby moving groups: a preliminary result using machine-learning based method"

In 1990s, coeval, co-moving, and gravitationally unbound stellar groups were discovered. Classified as “moving groups”, they have contributed on many important studies such as evolution of planetary systems and low-mass stars. In spite of their importance, currently identified moving groups have ambiguity which can cause problems in membership and the related researches. The objective and unbiased analysis of young nearby stars is required to solve this problem. We will perform 7-dimensional machine-learning based analysis using a large data-set of young nearby stars. Here, I present a preliminary result.
