Physical properties of the oEA star IV Cas

We present photometric and spectroscopic observing results of the oEA star IV Cas. Spectral types of the binary system are derived to be A3 (Teff = 8500 K) for the primary component and G9 (Teff = 5370 K) for the secondary. We detected two δ Scuti-type pulsation frequencies of f1 = 32.6894 c/d (cycles per day) and f2 = 36.6714 c/d, for the primary component.
