Scientific paper

In this work we build a grid of evolutionary tracks of massive stars of 23, 28, 30 and 33 solar masses with solar metallicity and mass loss, from ZAMS to presupernova. Our stars finish their life like RSG, BSG or WR stars, depending of their mass loss history. The stellar mass loss also modifies the circumstellar medium (CSM) during the star life and we model the complete CSM evolution with a hydrodinamical code (ZEUS-3D) during each evolutionary stage. We observe the formation of shells and bubbles surrounding the star depending of the evolutionary track of the star and the time that spends in each stage. The supernova (SN) shock wave interacts with this modified CSM. We also realized numerical simulations of their interaction.
