Scientific paper

From Data Release Two of Sloan Digital Sky Survey (SDSS DR2), 395 late-type spiral galaxies brighter than 15m in r band are selected. The correlations between the color gradients and other structural parameters of disks are investigated. It is shown that there is no correlation between the color gradients and absolute magnitude (mass); there are strong correlations between the color gradients and sizes of the disks, i.e., the larger the disks, the steeper the color gradients. There are also strong correlations between the color gradients and colors. The bluer the disks, the steeper the color gradients. It is also shown that the color gradients are strongly dependent on the surface brightness of disk. The disk with brighter surface exhibits steeper color gradients. In the end, the constraint of the correlations between the color gradients and other structural parameters of the disks in the late-type spiral galaxies on the star formation history is also discussed.
