Massive young stellar objects and outflow in the infrared dark cloud G79.3+0.3.

Abstract (from CDS):

G79.3+0.3 is an infrared dark cloud in the Cygnus-X complex that is home to massive deeply embedded young stellar objects (YSOs). We have produced a Submillimeter Array (SMA) 1.3 mm continuum image and 12CO line maps of the eastern section of G79.3+0.3 in which we detect five separate YSOs. We have estimated physical parameters for these five YSOs and others in the vicinity of G79.3+0.3 by fitting existing photometry from Spitzer, Herschel, and ground-based telescopes to spectral energy distribution models. Through these model fits we find that the most massive YSOs seen in the SMA 1.3 mm continuum emission have masses in the 5-6 M☉ range. One of the SMA sources was observed to power a massive collimated 12CO outflow extending at least 0.94 pc in both directions from the protostar, with a total mass of 0.83 M☉ and a dynamical timescale of 23 kyr.
