The unusual cometary star-forming region G110-13

We present far-IR, radio continuum, and spectral line observations of an unusual, highly elongated, comet-shaped molecular cloud, located ∼100 pc from the Galactic plane. The presence of three late B-type stars embedded within, or adjacent to, this low-mass (≃60 M ⊙ ) cloud implies a star-forming efficiency that may be as high as 30%. Several mechanisms that may have been responsible for its unusual morphology and high star-forming efficiency will be described and evaluated
