We obtained continous sequences of very high S/N echelle spectra of Vega in order to detect for the first time stellar pulsations in this star. Such a detection would lead to the discovery of a new type of pulsating stars as Vega, according to its position in the HR diagram, does not belong to any known class of pulsating stars. Adding seismology constraints to the many observational constraints available for this star would convert Vega as a prototype to study the effects of fast rotation on stellar structure therory. In this talk we present the progress of our ongoing work.
