| Abstract: | To investigate the dependence of the Holmberg effect of paired galaxies on three-dimensional separations, we have constructed
four subsamples characterized by three-dimensional separations s ≤ 50 kpc, 50 kpc < s ≤ 100 kpc , 100kpc < s ≤150kpc , and
150 kpc < s ≤ 200 kpc , respectively. In this study, linear correlation coefficients and surplus standard deviations of color
indices, luminosity, and size between two components of paired galaxies are calculated. It is found that there is a weak tendency
for correlation coefficients of color indices to increase with decreasing three-dimensional separations, but such a tendency
does not exist for ones of luminosity and size. We also note that there is no tendency for surplus standard deviations to
decrease with decreasing three-dimensional separations. This suggests that it is still very difficult to clearly affirm the
dependence of the Holmberg Effect of paired galaxies on three-dimensional separations. |
