Comparison of the values for the stellar radius R_⋆ obtained via SED fitting and GA analysis. The symbols and error bars correspond to the results obtained in Sects. 4 and 5; the dashed line represents the one-to-one correlation. The blue dots show the location of the targets for which we found evidence of a gaseous disk; the green triangles denote the stars that show IR excess longward of 2.5 μm and no emission lines in their spectra. The grey squares show the objects without disks. The values are consistent within the errors.
