  Arcuate infrared nebulae are ubiquitous throughout the Galactic Plane and are
candidates for partial shells, bubbles, or bowshocks produced by massive
runaway stars. We tabulate infrared photometry for 709 such objects using
images from the Spitzer Space Telescope (SST), Wide-Field Infrared Explorer
(WISE), and Herschel Space Observatory (HSO). Of the 709 objects identified at
24 or 22 microns, 422 are detected at the HSO 70 micron bandpass. Of these,
only 39 are detected at HSO 160 microns. The 70 micron peak surface
brightnesses are 0.5 to 2.5 Jy/square arcminute. Color temperatures calculated
from the 24 micron to 70 micron ratios range from 80 K to 400 K. Color
temperatures from 70 micron to 160 micron ratios are systematically lower, 40 K
to 200 K. Both of these temperature are, on average, 75% higher than the
nominal temperatures derived by assuming that dust is in steady-state radiative
equilibrium. This may be evidence of stellar wind bowshocks sweeping up and
heating --- possibly fragmenting but not destroying --- interstellar dust.
Infrared luminosity correlates with standoff distance, R_0, as predicted by
published hydrodynamical models. Infrared spectral energy distributions are
consistent with interstellar dust exposed to a either single radiant energy
density, U=10^3 to 10^5 (in more than half of the objects) or a range of
radiant energy densities U_min=25 to U_max=10^3 to 10^5 times the mean
interstellar value for the remainder. Hence, the central OB stars dominate the
energetics, making these enticing laboratories for testing dust models in
constrained radiation environments. SEDs are consistent with PAH fractions
q_PAH <1% in most objects.
