Notes. ⟨ U ⟩ is the luminosity averaged starlight
intensity;
Teff ≃ ⟨ U ⟩ 1/6 × 17.5 K
is the corresponding effective temperature of the grains;
fPAH is the PAH-to-total-dust mass fraction;
φ = LSF/(LISM + LSF)
is the luminosity fraction of the star-forming component.
is
the effective dust temperature corresponding to the peak of the far-IR bump using
Wien’s law.
