Mid-infrared Observations of Class I / Flat-spectrum Systems in Six Nearby Molecular Clouds


We have obtained new mid-infrared observations of 65 Class I /flat-spectrum (FS) objects in the Perseus, Taurus, Chamaeleon I and II, Ophiuchi, and Serpens dark clouds. These objects represent a subset of the young stellar objects (YSOs) from our previous near-infrared multiplicity surveys. We detected 45 out of 48 (94%) of the single sources, 16 out of 16… (More)
