MCG+08-22-082: A double core and boxy appearance dwarf lenticular galaxy
  as suspected to be a merger remnant
  We present a study on the dwarf lenticular galaxy MCG+08-22-082 (U141)
located in the Ursa Major cluster, which is blue centered, double cored, and
has a boxy appearance. Using publicly available data from the SDSS, we perform
an analysis of structural and stellar population properties of the galaxy and
the cores. We find that the light profile of U141 follows an exponential law.
U141 has a brightness Mr = -16.01 mag, and an effective radius Re = 1.7 kpc.
The boxiness parameter, a4/a, is mostly between 0 and -0.05 in the inner parts,
reaching an extreme of about -0.1. Double cores are seen at the center of U141
and each of these cores has a stellar mass of ~10^6 M_sun and the separation
between them is ~300 pc. Optical spectroscopy of these cores shows prominent
emission in H_alpha suggesting ongoing star forming activities. We interpret
these morphological properties to speculate that U141 is a merger remnant of
two disk galaxies. Thus, we might have caught an intermediate stage of merging
with the evidence of double cores in the center of the galaxy.
