The effect of convection on pulsational stability
G. Houdek
A review on the current state of mode physics in classical pulsators is presented. Two, currently in use, time-dependent convection models are compared and their applications on mo…
On the seismic age of the Sun
G. Houdek, D. O. Gough
We use low-degree acoustic modes obtained by the BiSON to estimate the main-sequence age of the Sun. The calibration is accomplished by linearizing the deviations from a…
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…
A study of convection with delta Scuti stars in open clusters: Pleiades
J. C. Suarez, E. Michel, G. Houdek +2
In this work we propose a preliminary seismic investigation of Scuti stars in the Pleiades cluster, focusing on potential diagnostics of convection and core-overshooting. Takin…
Amplitudes of stochastically excited oscillations in main-sequence stars
G. Houdek, N. J. Balmforth, J. Christensen-Dalsgaard +1
We present estimates of the amplitudes of intrinsically stable stochastically excited radial oscillations in stars near the main sequence. The amplitudes are determined by the bala…
