star-formation efficiency

star-formation efficiency

(SFE) The fraction of gas in a given cloud or cloud complex that eventually ends up in the form of stars. The rest is presumed to be dispelled by stellar winds, bipolar outflows, and supernova explosions before it can be incorporated into stars.

Combining the rate of star formation derived with WISE, and the gas mass measured by IRAM, the scientists get a measure of the star-formation efficiency.
The star-formation efficiency in these groups - the fraction of the gas and dust actually converted into stars - is about 25 percent, and this has fateful consequences for most new open clusters.
