Conclusions●●●We have detected ~1 day (0.25 P orb ) radial velocityoscillations in the companion star of LS 5039. Likelycaused by non-radial stellar oscillations. Must beaccounted for when deriving orbital parameters.We see radial velocity excursions in MWC 148 withamplitude a few tens km/s but no clear periodicity.Long-term variations in H α & H β parameters (EWs,FWHM, Centroid) with time-scale of >200 days.Orbital period or circumstellar disc cycles?
