Modelling pulsation amplitudes of ξ Hydrae
Amplitudes of stochastically excited oscillations of models of ξ Hydrae (HR4450) are presented. The theoretical results are compared with the recent measurements by an international group of… Expand
Ensemble Asteroseismology of Solar-Type Stars with the NASA Kepler Mission
- W. Chaplin, H. Kjeldsen, +56 authors T. Klaus
- Physics, Medicine
- Science
- 8 April 2011
Measurements of 500 Sun-like stars show that their properties differ from those predicted by stellar population models. In addition to its search for extrasolar planets, the NASA Kepler mission… Expand
Mode lifetimes of stellar oscillations - Implications for asteroseismology
- W. Chaplin, G. Houdek, C. Karoff, Y. Elsworth, R. New
- Physics
- 12 May 2009
Context. Successful inference from asteroseismology relies on at least two factors: that the oscillations in the stars have amplitudes large enough to be clearly observable, and that the oscillations… Expand
Damping rates and frequency corrections of Kepler LEGACY stars
- G. Houdek, M. Lund, R. Trampedach, J. Christensen-Dalsgaard, R. Handberg, T. Appourchaux
- Physics
- 30 April 2019
Linear damping rates and modal frequency corrections of radial oscillation modes in selected LEGACY main-sequence stars are estimated by means of a nonadiabatic stability analysis. The selected… Expand
The asteroseismic surface effect from a grid of 3D convection simulations - I. Frequency shifts from convective expansion of stellar atmospheres
- R. Trampedach, M. J. Aarslev, +4 authors M. Asplund
- Physics
- 8 November 2016
We analyse the effect on adiabatic stellar oscillation frequencies of replacing the near-surface layers in 1D stellar structure models with averaged 3D stellar surface convection simulations. The… Expand
Calibrating damping rates with LEGACY* linewidths
- G. Houdek
- Physics
- 14 February 2017
Linear damping rates of radial oscillation modes in selected Kepler stars are estimated with the help of a nonadiabatic stability analysis. The convective fluxes are obtained from a nonlocal,… Expand
A study of convection with delta Scuti stars in open clusters: Pleiades
- J. Suárez, E. Michel, G. Houdek, Y. Lebreton, F. P. Hernández
- Physics
- 5 April 2002
In this work we propose a preliminary seismic investigation of $\delta$ Scuti stars in the Pleiades cluster, focusing on potential diagnostics of convection and core-overshooting. Taking into account… Expand
Solar-like Oscillations and Activity in Procyon: A Comparison of the 2007 MOST and Ground-based Radial Velocity Campaigns
- D. Huber, T. Bedding, +8 authors W. Weiss
- Physics
- 14 February 2011
We compare the simultaneous 2007 space-based MOST photometry and ground-based radial velocity (RV) observations of the F5 star Procyon. We identify slow variations in the MOST data that are similar… Expand
