Fundamental parameters of eight Am stars: comparing observations with theory.

CATANZARO G. and RIPEPI V.

Abstract (from CDS):

In this paper we present a detailed analysis of a sample of eight Am stars, four of them are in the Kepler field of view. We derive fundamental parameters for all observed stars, effective temperature, gravity, rotational and radial velocities, and chemical abundances by spectral synthesis method. Further, to place these stars in the Hertzsprung-Russel diagram, we computed their luminosity. Two objects among our sample, namely HD 114839 and HD 179458, do not present the typical characteristic of Am stars, while for the others six we confirm their nature. The behaviour of lithium abundance as a function of the temperature with respect the normal A-type stars has been also investigated, we do not find any difference between metallic and normal A stars. All the pulsating Am stars present in our sample (five out of eight) lie in the δ Sct instability strip, close to the red edge.
