| 英文摘要 | Abstract In this work we report the discovery of two new stellar associations in close vicinity of the Sun at roughly 180 and 150 pc. These two associations, u Tau assoc and e Tau assoc, were detected based on their clustering in a multi-dimensional parameter space including α, δ, μα, μδ, and ? of Gaia. The fitting of pre-main-sequence model isochrones in their color–magnitude diagrams suggests that the two associations are of about 50 Myr old and the group members lower than ～0.8?M⊙ are at the stage of post-T Tauri. |
