VizieR Online Data Catalog: New young stars and brown dwarfs in Upper Sco (Luhman+, 2018)
Abstract
During a study of circumstellar disks in Upper Sco, Luhman & Mamajek (2012, J/ApJ/758/31) compiled a list of known members of the association. That list contained 863 sources, 181 of which comprised an initial sample of new members found through the survey that we are presenting in this work. Many additional members have been identified by subsequent surveys of Upper Sco. We have revised and expanded the compilation of members from Luhman & Mamajek (2012, J/ApJ/758/31) to account for those surveys and new membership constraints. We have obtained optical and near-IR spectra of candidate members of Upper Sco from the previous section to measure their spectral types and assess their membership. We also have observed a sample of stars that were previously known or suspected to be members to improve their spectral classifications and evidence of membership. These data were taken between 2009 and 2017 at the 1.5 m SMARTS and 4 m Blanco telescopes at the Cerro Tololo Inter-American Observatory (CTIO), the NASA Infrared Telescope Facility (IRTF), the Southern Astrophysical Research Telescope (SOAR), and the Gemini North and South telescopes.
