Mode Typing of the Dominant Mode in the Delta Scuti Star X Cae by Line Profile Moments
نویسندگان
چکیده
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.

Simultaneous intensive photometry and high resolution spectroscopy of δ Scuti stars IV. An improved picture of the pulsational behaviour of X Caeli
The δ Scuti star X Caeli has been the target of a simultaneous photometric (14 consecutive nights) and spectroscopic campaign (8 consecutive nights). From the analysis of light curves we were able to pick up 17 frequency components, most of which were already detected in two previous campaigns. The comparison with the results of the previous campaigns shows that while some terms are rather stab...
متن کاملLine profile analysis of the δ Scuti star HD 2724≡BB Phe: mode identification and amplitude variations
The line profile variations of the δ Scuti star HD 2724≡BB Phe were studied on the basis of new 189 high– resolution spectrograms covering 52 hours of observations on a baseline of 8.3 days. By combining these results with those of a previous campaign 13 pulsation modes were identified: 5 of them are both photometric and spectroscopic, 3 are purely spectroscopic and 5 purely photometric. For th...

متن کاملV. the High–degree Modes in the Pulsational Content of Bv Circini
We discuss here the pulsation properties of the δ Scuti star BV Circini on the basis of data obtained during a simultaneous photometric and spectroscopic campaign in 1996 and a spectroscopic one in 1998, and taking also advantage of the previous photometric observations by Kurtz (1981). Nine pulsation modes were detected from photometry and thirteen from spectroscopy; five of them are in common...
متن کاملA spectroscopic search for high azimuthal-order pulsation in broad-lined late F- and early G-stars
During 3 consecutive nights, 13 southern Fand Gtype dwarfs and giants outside the conventional δ Scuti instability strip were observed at high spectral (3 km/s) and medium temporal (10-15 min) resolution. The stars were selected for their reported broad spectral lines (v sin i≥ 40 km/s) so that pulsation in higher azimuthal-order nonradial harmonics could, via the rotational Doppler effect, rev...
