PULSATIONAL BEHAVIOR OF 44-TAURI

Two separate data sets of 44 Tauri, obtained at Merate and Ege Univers ity Observatories, were combined and analyzed in order to monitor its pulsational behaviour. This analysis gave a clue that the star might h ave experienced some variations in its pulsational behaviour within a year. Further solutions using Poretti et al. (1992) frequencies as adj ustables and the Ege University Observatory data resulted in seven fre quencies in the range 6.8974 c d-1 and 11.5190 c d-1 which gave a sati sfactory fit with the light curves. Furthermore, for six of the terms out of seven, the differences found in the frequencies with respect to Poretti et al. results exceed more than three times the relevant erro rs given therein. Differences could also be obtained on the amplitudes of three of the terms if the Poretti et al. frequencies were kept con stant in a solution with the present data. An attempt for mode identif ication led to three radial (fundamental, first and second overtones), two p1 and two p2 non-radial modes with a different order l.
