摘要

In the course of a comprehensive millimeter/submillimeter survey of massive-star-forming regions, the vicinities of a sample of 47 luminous IRAS sources were closely investigated with the Submillimeter Common-User Bolometric Array and the MPIfR bolometers in order to search for massive protostellar candidates. A particularly interesting object has been found in the surroundings of the bright far-infrared source IRAS 07029-1215. Follow-up line observations show that the object is cold, has a massive envelope, and is associated with an energetic molecular outflow. No infrared point source has been detected at its position. Therefore, it is a very good candidate as a member of the long-sought group of massive protostars.
