  The line profile variations of the Delta Scuti star HD 2724=BB Phe were
studied on the basis of new 189 high-resolution spectrograms covering 52 hours
of observations on a baseline of 8.3 days. By combining these results with
those of a previous campaign 13 pulsation modes were identified: 5 of them are
both photometric and spectroscopic, 3 are purely spectroscopic and 5 purely
photometric. For the first time it was possible to compare spectroscopic data
taken in two different seasons: 6 modes were found to be common to both
datasets and furthermore strong amplitude variations of the excited modes were
detected. The fit of the line profile variations with a model of non-radial
pulsating star allowed us to obtain a reasonable estimate of the inclination of
the rotational axis and to propose the l,m typing of the spectroscopic modes.
The frequency content resembles that of 4 CVn, a delta Sct star with similar
physical parameters.
