Abstract

The release of Gaia astrometric data has allowed for machine learning to locate hundreds of potentially new Galactic star clusters and moving groups. Our research is focused on one such association of stars, Theia 456. Theia 456 is a stellar filament of an estimated 468 stars that is within 1 kpc of the Sun, and our group’s preliminary analysis suggests stars in Theia 456 share similar compositions. Due to these properties, Theia 456 is considered primordial, resulting from the Galactic stellar formation process rather than the result of dynamical processes such as tidal stripping. Our research is focused on utilizing a python code we have developed to analyze positions, proper motions, and parallaxes of stars in the second data release (DR2) of the Gaia catalog to confirm or reject the stellar members of Theia 456. We endeavor to verify the validity of Theia 456 as a primordial stellar filament and possibly identify additional members of the association. This research will contribute to our understanding of the evolution of the Milky Way Galaxy.
