The Hα behavior in bright giant stars.

LEBRE A. and DE MEDEIROS J.R.

Abstract (from CDS):

We report high resolution spectroscopic observations of the Hα line profile for a sample of 32 bright giant stars with spectral type between F3II and G5II. By studying the link between the Hα behavior and the stellar rotation in such class of luminosity we have found no clear evidence that the rotational discontinuity established around F9II is related with the Hα profiles. No emission features, neither time variations or asymmetries on the Hα line profiles have been detected for the bright giants analysed in the present work.
