MULTIPLICITY OF THE PROTOSTAR SERPENS SMM 1 REVEALED BY MILLIMETER IMAGING

Show affiliationsThe Serpens SMM 1 region was observed in the 6.9 mm continuum with an angular resolution of about 0
6. Two sources were found to have steep positive spectra suggesting emission from dust. The stronger one, SMM 1a, is the driving source of the bipolar jet previously known, and the mass of the dense molecular gas traced by the millimeter continuum is about 8 M ☉. The newly found source, SMM 1b, positionally coincides with the brightest mid-IR source in this region, which implies that SMM 1b is yet another young stellar object. SMM 1b seems to be less deeply embedded than SMM 1a. SMM 1 is probably a protobinary system with a projected separation of 500 AU.
