摘要

As part of a deep near-infrared imaging survey for infrared point sources in Bok globules, we have discovered the first Bok globule showing evidence of harboring an aggregate of embedded objects. By the use of a near-infrared color-color diagram, a total of 12 objects seen toward this globule were found to exhibit near-infrared color excesses consistent with those of young stellar objects having intrinsic infrared excess emission due to circumstellar material. Four of these objects exhibit extended infrared emission similar to that seen surrounding other young stellar objects in Bok globules. The objects are contained in a region of about 3 arcmin estimated to correspond to about 0.1 pc~2. Together, these facts indicate that this group of stars forms an aggregate of young stellar objects contained in the globule.
