Space asteroseismology on later-type stars

Stars with substantial outer convective envelopes are expected to exhibit p-mode oscillations just as we observe on the Sun. We investigate how the excitation and damping rates of the oscillations, and hence the amplitudes of the resonant modes, might scale with stellar mass, particularly for later-type stars with masses somewhat smaller than that 1 M_o. We show how, with not unreasonable sized space-borne detectors, oscillations of such stars can be measured and we review the astrophysics that will be achieved with such a space mission.
