Seismic diagnostics of mixing beyond the convective core in intermediate mass main-sequence stars
B. L. Popielski, W. A. Dziembowski
We study prospects for seismic sounding the layer of a partial mixing above the convective core in main-sequence stars with masses in the 1.2 -- 1.9 solar mass range. There is an i…
Nonradial mode excitation as the cause of the Blazhko effect in RR Lyrae stars
W. A. Dziembowski, T. T. Mizerski
A significant fraction of RR Lyrae stars exhibits amplitude and/or phase modulation known as the the Blazhko effect. The oscillation spectra suggest that, at least in most of the c…
Inferring information about rotation from stellar oscillations
M. J. Goupil, R. Samadi, J. Lochard +2
The first part of this paper aims at illustrating the intense scientific activity in the field of stellar rotation although, for sake of shortness, we cannot be exhaustive nor give…
On application of multi-colour photometry of Scuti stars
J. Daszy{ń}ska-Daszkiewicz, W. A. Dziembowski, A. A. Pamyatnykh
In Scuti star models, the photometric amplitudes and phases exhibit a strong dependence on convection, which enters through the complex parameter, , which describes the bolo…
Nonlinearity of nonradial modes in evolved stars
Rafal M. Nowakowski, Wojciech A. Dziembowski
We show that in evolved stars, even at relatively low surface amplitudes, nonradial modes become strongly nonlinear in the hydrogen shell source, where the Brunt-Vaisala frequency…
Changes in solar oscillation frequencies during the current activity maximum: analysis and interpretation
W. A. Dziembowski, Philip R. Goode
We describe systematic changes in the centroid frequencies and the splitting coefficients as found using data from MDI on board SOHO, covering cycle 23. The data allow us to constr…
