Description

The results of observations done, in the last eight years, of the Intermidiate Polars (IP): EX Hya, V1223 Sgr, FO Agr and Ao Psc, are presented. The IP define a subclass of cataclysmic variable stars that present coherent oscillations in their optical and/or X-ray emission. The observations were done from Laboratorio Nacional de Astrofisica, in Itajuba (Brazil). The stability of oscillations in IP was analysed to study the nature of compact stars. (M.C.K.)
