Fig. 2.From: Modeling the infrared extinction toward the galactic centerComparison of the model extinction curve (red solid line) with the ~1–19μm IR extinction of the GC (blue squares) observed by Fritz et al. (2011). Also shown are the extinction curves of RV = 2.1 (dotted line, see Cardelli et al. (1989)), RV = 3.1 (dashed line, WD01) and RV = 5.5 (dot-dashed line, WD01) with the silicate absorption features added (Draine, 2003).Back to article page
