A search for T-Tauri stars based on the IRAS Point Source Catalog,. In a few cases the presence of a pre-planetary circumstellar disk can be inferred from an analysis of the relative velocity of forbidden lines with respect to the stellar rest velocity, but further observations are required to obtain better statistics on the presence of circumstellar disks.
