The delta Scuti phenomenon as seen through the Kepler data

A. Grigahcène

Abstract.
The first analysis of the long-awaited space data by asteroseismologists has raised more questions than it resolved (Grigahcene et al. 2010, ApJ). Specially the delta Scuti specialists have not been only surprised but also perplexed. The main aim of this work is to try to shed some light on Kepler's data on delta Scuti targets. First, we try to "clear land" in order to open new trails. Which may give rise to a new strategy that would provide a better understanding of the delta Scuti phenomenon. This is a substantive work going from the analysis of the light curves shape to the comparison to the most sophisticated theoretical models.
