An asteroseismic signature of helium ionization
G. Houdek, D. O. Gough
We investigate the influence of the ionization of helium on the low-degree acoustic oscillation frequencies in model solar-type stars. The signature in the oscillation frequencies…

On seismic signatures of rapid variation
G. Houdek, D. O. Gough
We present an improved model for an asteroseismic diagnostic contained in the frequency spacing of low-degree acoustic modes. By modelling in a realistic manner regions of rapid va…
