Abstract

Abstract: Using color indexes from SDSS and albedos from WISE we tested the homogeneity of 56 large Main belt families from Nesvorny list using the "color - albedo" plots. 25% of the analyzed families are non-homogeneous in terms of albedos and colors. Only two families (Flora and Vesta) contain low, moderate and high albedo asteroids, that are separated in a "color-albedo" plot. The fraction of the low albedo asteroids in bimodal families is not negligible (10-30%). Seven bimodal families may contain members from two overlapping families.
