Mode typing of the dominant mode in the Delta Sct star X Cae by line profile moments | | L. Mantegazza

6 Dec 1996 | | Subject: | astro-ph | | Affiliation: | Universita’ di Pavia and Brera Observatory, Milano, Italy), E. Poretti (Brera Observatory, Milano, Italy | | Abstract: | We use moment method developed by Balona (1987) to identify the dominant mode of the multimode pulsating Delta 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 degrees. The physical parameters corresponding to this mode are derived and discussed. | | Source: | arXiv, astro-ph/9612064 | | Services: | Forum | Review | PDF | Favorites | |
