Identifications of New Young Stellar Objects Associated with IRAS Point Sources. III. The Northern Galactic Plane
Abstract
A third list of new candidate young stellar objects found by searching the vicinities of IRAS positions along the galactic plane is presented. The list comprises 40 new objects in 39 fields with 2.2-micron magnitudes brighter than 10.5, and with near-infrared colors similar to those of fiducial objects such as GL 490. An additional 12 objects are identified as probable YSOs on the basis of incomplete data. Positions accurate to + or - 2 arcsec and deep red CCD pictures of 31 of the fields are given. Contemporaneous 10-micron observations allow an assessment of the reliability of the identifications; at least 80 percent of the near-infrared sources are directly related to the IRAS source, and the remainder are probably associated, but may not be the exciting sources of the regions.
