Modelling of the fast rotating δ Scuti star Altair.

SUAREZ J.C., BRUNTT H. and BUZASI D.

Abstract (from CDS):

We present an asteroseismic study of the fast rotating star HD187642 (Altair), recently discovered to be a δ Scuti pulsator. We have computed models taking into account rotation for increasing rotational velocities. We investigate the relation between the fundamental radial mode and the first overtone in the framework of Petersen diagrams. The effects of rotation on such diagrams, which become important at rotational velocities above 150km/s, as well as the domain of validity of our seismic tools are discussed. We also investigate the radial and non-radial modes in order to constrain models fitting the five most dominant observed oscillation modes.
