	abstract = {The Earth{\textquoteright}s outer core is a rotating ellipsoidal shell of compressible, stratified and self gravitating\&nbsp;fluid. As such, in the treatment of geophysical problems a realistic model of this\&nbsp;body needs to be considered. In this work, we consider compressible and stratified fluid core\&nbsp;models with different stratification parameters, related to the local Brunt-Vaisala frequency,\&nbsp;in order to study the effects of the core{\textquoteright}s density stratification on the frequencies of some\&nbsp;of the inertial-gravity modes of this body. The inertial-gravity modes of the core are free\&nbsp;oscillations with periods longer than 12 hr. Historically, an incompressible and homogeneous\&nbsp;fluid is considered to study these modes and analytical solutions are known for the frequencies\&nbsp;and the displacement eigenfunctions of a spherical model. We show that for a compressible\&nbsp;and stratified spherical core model the effects of non-neutral density stratification may be\&nbsp;significant, and the frequencies of these modes may change from model to model....},
