We propose to observe using the IRS a sample of 92 mostly F and G stars with well-characterized stellar photospheres to bridge the gap between the later spectral type T Tauris and the earlier type Herbig Ae/Be stars. Silicate dust properties of disks around F and G stars should be intermediate between those of classical T Tauris and Herbig Ae/Be systems. Because disk photospheric features have been observed in K and M type T Tauri star spectra and because the stellar photospheres of our sample of F and G type stars show no molecular absorption, Early T Tauri Stars are crucial in exploring disk photospheres. Also, the lack or presence of PAH features and their qualities should help give insight into the origin and nature of PAH dust in disks around young stars. In addition, spectra of these Early T Tauri stars can probe dust settling and disk structural evolution in this population. Young F and G stars, being of similar spectral type and mass to our Sun, might also shed light on the formation of our Solar System.
