Pulsation models of O-rich and C-rich long period variables

Abstract

The intrinsic variability of luminous red giants is an observable providing important information about stellar structure and evolution. Our aim is to provide a solid theoretical background to the wide amount of data coming from present and future variability surveys. We present here the first comparison between long period variables in the LMC (from OGLE-III) and our grid of pulsation models computed for a wide range of stellar parameters and input physics.
