McGregor, P. J. ; Persson, S. E. ; Cohen, J. G. Abstract The results of scans of 13 compact objects in the spectral region 0.6-1 micron are reported. The data were gathered using CCD detectors with 20 A resolution directed at the embedded IR sources. The survey was performed on five nights in 1982-83 with the double spectrograph on the Hale 5 m telescope. The objects observed were GL 490, GL 437S, GL 961, GL 434W, IC 2848A, S106/IRS3, M17/IRS1, S235G, M8E, 297, MW7 349, V645 Cyg, and the fan nebula region of GL989. All the objects displayed extreme reddening and Paschen series hydrogen emission lines, with several displaying O I and CA II triplet lines. The characteristics were similar to other sources with IR excess, suggesting similar physical phenomena. The 1 micron continuum possible arises from scattering and circumstellar shell emission contributions. O I lines are associated with Lyman beta fluorescence. The presence of singly ionized Ca II emissions suggests that the effective temperatures of the regions are no more than 5000 K.
