| 英文摘要 | Two-dimensional bulge/disk light decomposition with GIM2D in both the r- and g-bands has been applied to a sample of 129 early-type galaxies brighter than 13.5 magnitude in the r-band, selected from the Sloan Digital Sky Survey Data Release 2. Intensity-weighted Fourier coefficient < a(4)/a > was also derived for each sample galaxy. Our analysis shows that there are correlations between bulge-to-total light ratio (BIT) with bulge Sersic index n(B) and between bulge and disk scale sizes. Isophotal shape parameter < a(4)/a > is not correlated with BIT and nB. Both bulge and disk components satisfy a color-magnitude relation. The kappa space Fundamental Plane analysis shows that galaxies with larger BIT tend to lie tighter and closer to the line of kappa(1) + kappa(2) = 8 (the so-called "zone of avoidance") than the galaxies with smaller BIT. It indicates that existence of the disk component may lead to scatter of the distribution on the Fundamental Plane. Our analysis also shows that kappa(1) + kappa(2) correlates with (g-r) color and BIT, but does not correlate with < a(4)/a > for early-type galaxies. The fitted parameters and other retrieved parameters used in this paper for all sample galaxies are available online. |
