cds-question@unistra.frspectroscopic-binary-starsopen-star-clustersvisible-astronomyWe have developed a new method for spectral analysis of binaries. Our method successfully identifiesSB2 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 with vsin(i) from 1 to 330km/s in the open cluster M11. 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.2022MNRAS.510.1515Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/510/1515CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/128/255 : Proper motions in M 11 (Su+ 1998)J/MNRAS/310/982 : UBVI CCD Photometry of M11 - II.
