Properties and Structural Features of Early-type Disk Galaxies with Multi-tier Disks

Abstract

The results of photometric decomposition of surface brightness distributions in 85 early-type unbarred galaxies are presented. The SDSS r-images are analysed. Double-tiered exponential disks are found in all galaxies which are studied; the statistics of the disk parameters is derived.
