VizieR Online Data Catalog: Circumstellar disks in the Upper Sco association (Esplin+, 2018)
Abstract
Our survey for new disk-bearing members of Upper Sco is based primarily on data from the WISE mission (Wright et al. 2010AJ....140.1868W). Data from the fully cryogenic phase and the entire 13-month mission were released in the WISE All-Sky Source Catalog (Cat. II/311) and the AllWISE Source Catalog (Cat. II/328), respectively. We initially used the WISE All-Sky Catalog for our survey. We repeated our analysis with the AllWISE Source Catalog when it was released. We performed spectroscopy on 233 candidate disk-bearing stars to measure their spectral types and check for signatures of youth. The spectra were taken with SpeX (Rayner et al. 2003PASP..115..362R) at the NASA Infrared Telescope Facility (IRTF), the Goodman High Throughput Spectrograph at the Southern Astrophysical Research Telescope (SOAR), and the Cerro Tololo Ohio State Multi-Object Spectrograph (COSMOS) and the Astronomy Research using the Cornell Infra Red Imaging Spectrograph (ARCoIRIS) at the 4 m Blanco telescope at the Cerro Tololo Inter-American Observatory (CTIO). To identify the circumstellar disks in Upper Sco and to classify their evolutionary stages, we have compiled all available mid-IR photometry from Spitzer and WISE for the catalog of 1631 known members from Luhman et al. (2018AJ....156...76L), which includes the new members found in this study.
