Context. The theoretically studied impact of rapid rotation on stellar evolution needs to be confronted with the results of high resolu-tion spectroscopy-velocimetry observations. Early type stars present a perfect laboratory for these studies. The prototype A0 star Vega has been extensively monitored in the last years in spectropolarimetry. A weak surface magnetic field has been detected, potentially leading to a (yet undetected) structured surface. Aims. The goal of this article is to present a thorough analysis of the line profile variations and associated estimators in the early-type standard star Vega (A0) in order reveal potential activity tracers, exoplanet companions and stellar oscillations. Methods. Vega was monitored in high-reso...
