Pulsational behaviour of 44 Tauri.

Two separate data sets of 44 Tauri, obtained at Merate and Ege University Observatories, were combined and analyzed in order to monitor its pulsational behavior. This analysis gave a clue that the star might have experienced some variations in its pulsational behavior within a year. Further solutions using Poretti et al. (1992) frequencies as adjustables and the Ege University Observatory data resulted in seven frequencies in the range 6.8974 c/d and 11.5190 c/d which gave a satisfactory 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 errors given therein. Differences could also be obtained on the amplitudes of three of the terms if the Poretti et al. frequencies were kept constant in a solution with the present data. An attempt for mode identification led to three radial (fundamental, first and second overtones), two p₁ and two p₂ non-radial modes with a different order l.
