Fig. 4


IRAC color–color diagrams from our synthetic photometry for the 36 YSO SEDs at Stages I, II, and III (from left to right columns) with stellar masses of 0.2, 2.0, and (from top to bottom rows), and disk inclinations of 18.2° (asterisks), 49.5° (diamonds), 81.4° (filled circles), and 87.1° (pluses). The SEDs are progressively reddened up to AKS = 8 mag using the broad-bump case of our extinction law. Color coding represents different AKS values (red for 0 mag). All [3.6]−[4.5] and [5.8]−[8.0] colors are relative to those for AKS = 0, and each sequence of reddening is shifted both vertically and horizontally for clear presentation. Insets show magnified CC diagrams for AKS of up to 1 mag. Vertical lines from AKS = 0 mag are also drawn as a guide for eyes.
