Cluster AgeS Experiment (CASE): SX Phe stars from the globular cluster Omega Centauri
A. Olech, W. A. Dziembowski, A. A. Pamyatnykh +4
We present an analysis and interpretation of oscillation spectra for all 69 SX Phoenicis stars discovered in the field of the cluster. For most of the stars we have reliable absolu…

Asteroseismology and forced oscillations of HD 209295, the first member of two classes of pulsating star
G. Handler, L. A. Balona, R. R. Shobbrook +9
We report the discovery of both intermediate-order gravity mode and low-order pressure mode pulsation in the same star, HD 209295. It is therefore both a gamma Doradus and a delta…

Pulsational instability domain of Delta Scuti variables
A. A. Pamyatnykh
An updated theoretical instability domain of the Delta Scuti star models in the Hertzsprung-Russell diagram, in the log g - log Teff diagram and in diagrams for dereddened uvby-bet…
