We present high spectral resolution (v~12-16 km/s) Brackett line spectroscopyof the blue compact dwarf galaxy Henize 2-10 made with NIRSPEC on the KeckTelescope. The spatial resolution is seeing limited, at 1". We detect twodistinct kinematic features separated by approximately 3", with heliocentricvelocities of ~860 and ~890 km/s. In addition to a narrow core, the lineprofiles also display a broad, low intensity feature on the blue side of thecentroid, which we attribute to an outflow. This may be a sign of aging in theclusters. We compare to archival high resolution Very Large Array (VLA) data at1.3 cm, and find that the centimeter wavelength emission is resolved into sixsources. These radio sources are organized into two larger groups, which weassociate with the two kinematic peaks in the Brackett spectrum. We estimate aLyman continuum rate of at least 7 x 10^52 s^-1, with a corresponding stellarmass of 6 x 10^6 M_sun is required to ionize the nebulae. We also estimate thesize of the nebulae from the radio continuum brightness and find that theobserved sources probably contain many HII regions in smaller, unresolvedclumps. Brackett line profiles have supersonic line widths, but, aside from theblue wing, are comparable to line widths observed in Galactic ultracompact HIIregions, which are excited by a single star, or a few stars.
