Abstract:
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.
The goal of this work is to elucidate the nature of IRS 1 and IRS 3,
and study their interactions with the surrounding medium.
Description:
One of the first observations with the Submillimeter Array with six
antennas on the array. We observed the 1.3mm continuum and CO(2-1)
line toward one high-mass protostellar object candidate.
