Caption: Fig. 2.

Spitzer IRS spectra of TDG‐N. Top: IRS‐SL spectrum showing strong PAH features and 0–0 S(3) 9.7 μm molecular hydrogen. Bottom: Combined IRS‐SH and IRS‐LH spectrum showing PAHs and fine‐structure lines. The flattening of the continuum emission beyond ﹩\lambda > 20﹩ μm signifies the absence of a dominant cool 40 K dust component.
