UYSO 1 - An Extremely Young Massive Stellar Object
Abstract
In the course of a comprehensive mm/submm survey of massive star-forming regions, a particularly interesting object has been found in the surroundings of the bright FIR source IRAS 07029-1215, in a distance of 1 kpc. The object -- named UYSO 1 (Unidentified Young Stellar Object 1) -- is cold (T=40 K), it has a massive envelope, and it is associated with an energetic molecular outflow. No infrared point source has been detected at its position for wavelengths below 20 micron. Therefore, it is a very good candidate for a member of the long searched for group of massive protostars.
