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 approximately 100 pc from the Galactic plane. The presence of three late B-type stars embedded within, or adjacent to, this low-mass (almost-equal-to 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. Although ram-pressure resulting from the rapid motion of this cloud through the interstellar medium could explain its streamlined appearance, there is evidence that G110 - 13 is the compression front formed by a recent cloud collision.
