Scientific paper

We present preliminary results derived from the data obtained during three observing campaigns in 2000, 2001 and 2007, of the δ Sct-type variable star HR 4555, at Sierra Nevada Observatory, Spain. In all the cases, simultaneous uvbyβ photometry was carrried out. The analysis of the data was performed in the v band, by means of the Fourier Transform method, and results are shown. The intrinsic b-y, m_1 and c_1 values are derived and the physical parameters of this star are determined.
