A CATALOG OF PRE-MAIN-SEQUENCE EMISSION-LINE STARS WITH IRAS SOURCE ASSOCIATIONS

To aid in finding pre-main-sequence (PMS) emission-line stars that might have dusty circumstellar environments, we have identified 361 PMS stars that are associated with 304 separate IRAS sources. These stars include 200 classical T Tauri stars, 25 weak-lined (naked) T Tauri stars, 56 Herbig Ae/Be stars, six FU Orionis stars, and two SU Aurigae stars. All six of the FU Orionis stars surveyed by IRAS were detected. Of the PMS- IRAS Point Source Catalog (PSC) associations, 90 are new and are not noted in the PSC. The other 271 entries include 104 that are correctly identified in the PSC but have not yet appeared in the literature, 56 more that can be found in both the PSC and in the published and unpublished literature, and 111 that are in the literature but not in the PSC. Spectral slope diagrams constructed from the 12, 25, and 60 μm flux densities reveal unique distributions for the different PMS subclasses; these diagrams may help identify the best candidate PMS stars for observations of circumstellar dust.
