New observations with high spectral resolution and S/N ratio will be obtained with the new FEROS spectrograph and 1,5m ESO telescope of the La Silla Observatory. Simultaneous observations of lines formed under very different physical conditions will be used to model the dependency of effective temperature and log g on stellar latitude in the presence of very rapid rotation and to map atmospheric response to the NRP. This is enabled by the advent of a new analysis package (BRUCE-KYLIE, Twnsend 1997) which includes the effects of rapid rotetion on nonradial pulsation on the basis of state-of-the-art physics. Comparison of observed and synthetic line profiles provides NRP parameters and enables to apply methods of asteroseismology. The preliminary application of BRUCE to some FEROS reconnaissance data shows to be a realistically achievable goal."@en . .
