Double-lined spectroscopic binaries in M11
  We have developed a new method for spectral analysis of binaries. Our method
successfully identifies SB2 candidates from high-resolution Gaia-ESO spectra.
Compared to the commonly used cross-correlation function analysis, it works for
binaries with rapidly rotating components. We test our method on synthetic and
observational spectra of BAFG-stars in the open cluster M 11. We confirm five
previously detected SB2 candidates and find 19 new ones. For three SB2
candidates we find circular orbits and obtain dynamical mass ratios.
