Two new stellar associations in vicinity of the Sun
Listed in IVOA Registry (Virtual Observatory)
In this work we report the discovery of two new stellar associations in close vicinity of the Sun at roughly 180 and 150pc.
Description
These two associations, u-Tau assoc and e-Tau assoc, were detected based on their clustering in a multi-dimensional parameter space including {alpha}, {delta}, {mu}_{alpha}_, {mu}_{delta}_, and \bar{omega} of Gaia. The fitting of pre-main-sequence model isochrones in their color-magnitude diagrams suggests that the two associations are of about 50Myr old and the group members lower than ~0.8M_{sun}_ are at the stage of post-T Tauri.
