Mode typing of the dominant mode in the Delta Sct star X Cae by line   profile moments
  We use moment method developed by Balona (1987) to identify the dominant mode of the multimode pulsating Delta Scuti star X Cae. It is shown as a l=1 and m=-1 non-radial mode gives a satisfactory fit of the amplitudes and phases of light and line moments variations provided that the rotational axis has i<45 degrees. The physical parameters corresponding to this mode are derived and discussed.
