Solo dwarfs II: The stellar structure of isolated Local Group dwarf
  galaxies
  The Solo (Solitary Local) Dwarf Galaxy survey is a volume limited, wide-field
g- and i- band survey of all known nearby (<3 Mpc) and isolated (>300 kpc from
the Milky Way or M31) dwarf galaxies. This set of 44 dwarfs are homogeneously
analysed for quantitative comparisons to the satellite dwarf populations of the
Milky Way and M31. In this paper, an analysis of the 12 closest Solo dwarf
galaxies accessible from the northern hemisphere is presented, including
derivation of their distances, spatial distributions, morphology, and extended
structures, including their inner integrated light properties and their outer
resolved star distributions. All 12 galaxies are found to be reasonably well
described by two-dimensional Sersic functions, although UGC 4879 in particular
shows tentative evidence of two distinct components. No prominent extended
stellar substructures, that could be signs of either faint satellites or recent
mergers, are identified in the outer regions of any of the systems examined.
