VizieR Online Data Catalog: SACY. V. Multiple systems (Elliott+, 2014)
Abstract
Radial velocity values of approximately 250 pre-main sequence stars were calculated from the cross-correlation technique using high-resolution spectra from UVES and FEROS. We identified single-lined spectroscopic binaries (SB1s) and double- and triple-lined spectroscopic binaries (SB2s/SB3s) using these values in combination with available catalogue data. We used the number of identified systems to derive the fraction of spectroscopic binaries in our sample and comment on the implications in the context of star formation.
