"Follow-up of Young Stars Identified with BANYAN Σ: New Low-mass Members of Nearby Moving Groups." <i>The Astrophysical Journal,</i> 941, no. 1 (2022) IOP Publishing: https://doi.org/10.3847/1538-4357/ac8b78.https://hdl.handle.net/1911/114268The characterization of moving groups offers a powerful means to identify large populations of young stars. In this paper, we present a sample of follow-up observations for 56 systems that have previously been proposed as members of young stellar associations through the application of the BANYAN Σ kinematic classification tool. Our measurements, which probe seven different associations, provide a sample of 39 stellar systems that either are confirmed or appear consistent with being young members of their respective associations. Nineteen of these are single M dwarfs. This sample expands our knowledge of Upper Centaurus Lupus, Coma Berenices, and AB Doradus Major to cooler temperatures and also significantly increases the known population of the Carina-Near association. The young systems present excellent targets for future planet searches and would also be valuable for studies of star formation and evolution. Additionally, we find two stellar systems that show indications of being rare instances of late-stage circumstellar accretion. Lastly, our follow-up measurements serve as a test of BANYAN Σ, finding an overall contamination rate that is consistent with previous findings (29% for systems with RV measurements, 37% without).engOriginal content from this work may be used under the terms of the Creative Commons Attribution 4.0 licence.
