WebbABSTRACT. The Milky Way has been described as an anaemic spiral, but is its star formation rate (SFR) unusually low when compared to its peers? To answer this question, we define a sample of Milky Way analogues (MWAs) based on stringent cuts on the best literature estimates of non-transient structural features for the Milky Way. WebbThe determination of the global star formation rate (SFR) for the Milky Way is rigorously based on measurements of the global parameters of several local star-forming regions. …

However, the fraction of a GMC's gas that ends up in stars before the cloud is disrupted is rather small, with typical estimates in the Milky Way ∼2%, e.g., Evans ( 1991 ). A related question regards the rate at which stars form in GMCs.
