Resumen:

We calculate the mass-to-light versus color relations (MLCRs) derived from the spatially-resolved star formation history (SFH) of a sample of galaxies from the integral field spectroscopy CALIFA survey. Using full spectral fitting methods we derive the stellar mass (M?) and combine these results with observed and synthetic colors in optical broad bands. We obtain the radial structure of the mass-to-light ratio (M/L) at several bands and study the MLCRs. Our sample covers a wide range of Hubble types, with stellar masses ranging from M? ~ 108.4 to 1012 M. © Proceedings of the 13th Scientific Meeting of the Spanish Astronomical Society - Highlights of Spanish Astrophysics X, SEA 2018.
