Abstract:
    We present the distribution of a statistical sample of nearby galaxies
    in the κ-space 
    ({kappa1}∝logM, κ2∝log(Ie)3*M/L, 
     κ3∝M/L). 
    Our study is based on near-IR (H-band: {lamdba}=1.65µm)
    observations, for the first time comprising early- and late-type
    systems. Our data confirm that the mean effective dynamical
    mass-to-light ratio M/L of the E+S0+S0a galaxies increases with
    increasing effective dynamical mass M, as expected from the existence
    of the Fundamental Plane relation. Conversely, spiral and Im/BCD
    galaxies show broad distribution in M/L with no detected trend of M/L
    with M, the former galaxies having M/L values about twice larger than
    the latter, on average. For all the late-type galaxies, the M/L
    increases with decreasing effective surface intensity Ie, consistent
    with the existence of the Tully-Fisher relation.
