Abstract

Context.IRAS 20343+4129 was suggested to harbor one of the most massive and embedded stars in the Cygnus OB2 association, IRS 1, which seemed to be associated with a north-south molecular outflow. However, the dust emission peaks do not coincide with the position of IRS 1, but lie on either side of another massive Young Stellar Object (YSO), IRS 3, which is associated with centimeter emission.
