000005157 520__ $$aBy means of a study based on multi-epoch high-resolution spectra of 83 A         --F-type candidate hybrid pulsating stars from the Kepler         mission, collected at various observatories, we derive a (lower)         estimate of the fraction of hybrid stars which belong to         spectroscopic binary and multiple systems. In the first part of         the study (49 hybrid stars) we derived a global spectroscopic         multiplicity fraction of 27\% (Lampens et al. 2018). In the         second part we intend to obtain the same information for another         46 candidates. From a preliminary classification of 43 new         targets, we are finding a spectroscopic multiplicity fraction of         $\sim$30\textbackslash\%. Spectroscopic observations are on-         going. As a bonus, we identified systems for which a combined         analysis of time delays (TDs) with radial velocities (RVs)         enable one to derive accurate orbital elements and mass ratios         and also an identification of the pulsating component.         Furthermore, we will analyse the low-frequency regions of the         periodograms of these stars using the exquisite data collected         by Kepler.
