The structure of stellar disks in isolated lenticular galaxies
  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 one-meter
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 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 profiles shapes with our
previous sample of the 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.
