Query: Acoustic and buoyancy modes throughout stellar evolution - Seismic
  properties of stars at different stellar ages and masses   Parameter regions in which stars can become pulsationally unstable are found
throughout the Hertzsprung-Russel diagram. Stars of high, intermediate, low and
very low masses may cross various instability regions along their paths of
evolutionary sequences. In describing them, I give special consideration to
hybrid pulsational characteristics that are particularly valuable for
asteroseismic investigations, to Pdot measurements that allow us to directly
follow the stellar evolutionary changes in some stars, and to new research
results that stand out with respect to previous consensus.
