Asteroseismology, the study of stellar interiors on the basis of observations of multi-mode stellar oscillations, extends over a large part of the Hertzsprung-Russell diagram. The recently discovered EC14026 stars promise information about the properties of stars on the horizontal branch. Solar-like oscillations excited stochastically by convection have been tentatively identified in a few cases. Promising examples are giant stars, where the expected amplitudes may make ground-based observations of the oscillations relatively straightforward. Major advances can be expected from the upcoming asteroseismic space projects under development or study, including the Eddington mission adopted by ESA as a ‘reserve mission’ in the recent round of selections.
