We use moment method developed by Balona (1987) to identify the dominant mode of the multimode pulsating δ Scuti star X Cae. It is shown as a l = 1 and m = −1 non-radial mode gives a satisfactory fit of the amplitudes and phases of light and line moments variations provided that the rotational axis has i ≥ 45. The physical parameters corresponding to this mode are derived and discussed.

Findings of a few recent asteroseismic studies of the main-sequence pulsating stars, as performed in Wojciech Dziembowski’s group in Warsaw and in Michel Breger’s group in Vienna, are briefly presented and discussed. The selected objects are three hybrid pulsators ν Eridani, 12 Lacertae and γ Pegasi, which show both β Cephei and SPB type modes, and the δ Scuti type star 44Tauri. Session: STARS ...
