Abstract: We investigate the mass-to-light versus colors relations (MLCRs) derived from the spatially-resolved star formation history (SFH) of nearly 500 galaxies observed with integral field spectroscopy in the CALIFA survey. Our method combines the full spectral fitting with different sets of stellar populations models to derive the stellar mass and the stellar mass surface density with observed and synthetic colors in optical broad bands. This method allows to get the radial structure of the mass-to-light ratio (M/L) for different bands, and their gradients, and to study the spatially-resolved MLCRs.
