A very young object close to IRAS 07029-1215 (UYSO1)
UYSO1 (J. Forbrich) close to IRAS 07029-1215 is one example from a comprehensive millimeter/submillimeter survey of massive star-forming regions (B. Posselt, Diploma thesis, University Jena). A bipolar, massive high-velocity outflow powered by a very deeply embedded source without any NIR/MIR/FIR counterpart point to a very young stellar object as the originating source.
More details you will find in "An Extremely Young Massive Stellar Object near IRAS 07029-1215" (Forbrich, Schreyer, Posselt et al. 2004, ApJ 602, p. 843).
