HI observations of IC 10 with the DRAO synthesis telescope
  HI observations of the nearby blue compact dwarf galaxy IC 10 obtained with
the Dominion Radio Astrophysical Observatory synthesis telescope (DRAO), for a
total integration of $\sim$1000 hours, are presented. We confirm the NW faint
21 cm HI emission feature discovered in GBT observations. The HI feature has an
HI mass of 4.7 $\times 10^{5}$ M$_{\odot}$, which is only $\sim$ 0.6$\%$ of the
total HI mass of the galaxy (7.8 $\times 10^{7}$ M$_{\odot}$). In the inner
disk, the rotation curve of IC 10 rises steeply, then flattens until the last
point where it rises again, with a maximum velocity of 30 km s$^{-1}$. Based on
our mass models, the kinematics of the inner disk of IC 10 can be described
without the need of a dark matter halo. However, this does not exclude the
possible presence of dark matter on a larger scale. It is unlikely that the
disturbed features seen in the outer HI disk of IC 10 are caused by an
interaction with M 31. Features seen from our simulations are larger and at
lower surface density than can be reached by current observations. The higher
velocity dispersions seen in regions where several distinct HI features meet
with the main core of IC 10 suggests that there is ongoing accretion.
