Mid-IR size versus stellar luminosity for our sample. Color of the symbols indicates the object type: Herbig Ae (blue), T Tauri (red), and eruptive (orange). To extend the luminosity coverage, Herbig Be sources from Menu et al. (2015) are also plotted (gray diamonds). The radii that correspond to temperatures of 250 K and 900 K for optically thin gray dust are overplotted with red and blue dashed lines, respectively. The individually marked objects are discussed in Sect. 4.2.
