We present an analysis of the observations of HD 51106 and HD 50747 by thesatellite CoRoT, obtained during its initial run, and of the spectroscopicpreparatory observations.  AIMS: We complete an analysis of the light curve, extract the mainfrequencies observed, and discuss some preliminary interpretations about thestars.  Methods: We used standard Fourier transform and pre-whitening methods toextract information about the periodicities of the stars.  Results: HD 51106 is an ellipsoidal binary, the light curve of which can becompletely explained by the tidal deformation of the star and smaller secondaryeffects. HD 50747 is a triple system containing a variable star, which exhibitsmany modes of oscillation with periods in the range of a few hours. On thebasis of this period range and the analysis of the physical parameters of thestar, we conclude that HD 50747 is a Gamma-Doradus star.
