Determining star formation thresholds from observations

Khullar, Shivan; Krumholz, Mark; Federrath, Christoph; Cunningham, Andrew J.


Most gas in giant molecular clouds is relatively low density and forms star inefficiently, converting only a small fraction of its mass to stars per dynamical time. However, star formation models generally predict the existence of a threshold density above which the process is efficient and most mass collapses to stars on a dynamical time-scale. A number of authors have proposed observational techniques to search for a threshold density above which star formation is efficient, but it is unclear...[Show more]
