Description
We use Herschel Space Observatory data to place observational
constraints on the peak and Rayleigh-Jeans slope of dust emission
observed at 70-500 μm in the nearby spiral galaxy M81. We find that
the ratios of wave bands between 160 and 500 μm are primarily
dependent on radius but that the ratio of 70 to 160 μm emission shows
no clear dependence on surface brightness or radius. These results along
with analyses of the spectral energy distributions imply that the
160-500 μm emission traces 15-30 K dust heated by evolved stars in
the bulge and disc whereas the 70 μm emission includes dust heated by
the active galactic nucleus and young stars in star forming regions.
