Rydgren, A. E. ; Schmelz, J. T. ; Vrba, F. J. Abstract Evidence is found for a correlation between the color excess E(V-I) and the IR color H-K for T Tauri stars in the Taurus and NGC 2264 regions, through nearly-simultaneous BVRI and JHKL photometry. This phenomenon may be understood as a circumstellar reddening effect, and suggests that some of the observed V-I reddening in typical T Tauri stars is not interstellar in origin. Very narrow intrinsic loci of the Taurus region T Tauri stars in the (J-H, H-K) and (H-K, K-L) diagrams are found upon correction for interstellar reddening, consistent with circumstellar dust shell models with maximum dust temperatures of about 1300 K. No hot interstellar dust is found in two late-type pre-main sequence stars with weak line emission first noted by Feigelson and DeCampi (1981) as X-ray sources.
