Description
We present a project to study the stellar populations in the outskirts of spiral galaxies. We analyse the possible different radial mixing processes characterising different luminosity profiles and morphologies. This study makes use of the IFU spectroscopic data of the CALIFA collaboration. We have selected a sample of around 60 spiral galaxies from the CALIFA sample. This survey is providing us with unprecedented data which allow us to obtain stellar parameters and break the age-metallicity degeneracy up to large galactocentric radii. In addition, we are characterising the radial surface brightness and colour profiles of the galaxies in the g, r and i SDSS bands. In this work we study five galaxies with different luminosity profiles. We confirm that we can successfully obtain information about the stellar population in the outer parts of the galaxies. So far, we find no differences in the stellar age and metallicity distributions between barred and unbarred galaxies or among different surface brightness profile types.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta
