Asteroseismology of stars on the upper main sequence

Abstract

I review the properties of pulsators located on the upper main sequence in the HR diagram and discuss asteroseismic inferences on the internal structure of stars of spectral type A and B. Special attention is given to the problem of uncertainties in stellar opacities in modelling.Comment: 15 pages, 3 figures, accepted for publication in the proceedings of the 2011 Frank N.
