Description
Summary:Within the framework of the Cowling approximation, we present the frequencies of the f (fundamental), p 1 (first pressure) and g (gravitational) of quadrupolar oscillation modes of compact objects constructed using different equations of state. Special attention will be put in hybrid stars, formed by a quark core and a hadronic envelope. In this context, g modes are only present if a sharp first order phase transition occurs between hadronic and quark phases.
