Abstract (from CDS):

We use an updated method for the detection of double-lined spectroscopic binaries (SB2s) using Vsin i values from spectral fits. The method is applied to all spectra from Large sky Area Multi-Object fiber Spectroscopic Telescope Medium Resolution Survey. Using this method, we detect 12 426 SB2 candidates, where 4321 are already known and 8105 are new discoveries. We check their spectra manually to minimize possible false positives. We also detect several cases of contamination of the spectra by solar light. Additionally, for candidates with multiple observations, we compute mass ratios with systemic velocities and determine Keplerian orbits. We present an updated catalogue of all SB2 candidates together with additional information for some of them in separate data tables.
