The structure of stellar disks in isolated lenticular galaxies.

SIL'CHENKO O.K., KNIAZEV A.Y. and CHUDAKOVA E.M.

Abstract (from CDS):

We have obtained imaging data in two photometric bands, g and r, for a sample of 42 isolated lenticular galaxies with the Las Cumbres Observatory 1 m telescope network. We have analyzed the structure of their large-scale stellar disks. The parameters of surface-brightness distributions have been determined including the radial profile shapes and disk thicknesses. After inspecting the radial brightness profiles, all of the galaxies have been classified into pure exponential (Type I), truncated (Type II), and antitruncated (Type III) disks. By comparing the derived statistics of the radial profile shapes with our previous sample of cluster S0s, we noted a prominent difference between stellar disks of S0s galaxies in quite rarefied environments and in clusters: it is only in sparse environments that Type II disks, with profile truncations, can be found. This finding implies probable different dynamical history of S0 galaxies in different environments.
