Question

In a 2008 paper, Troland and Crutcher observed the Zeeman effect in the cores of these objects, computing the ratio of turbulent to magnetic energy within them. The velocity dispersion of these objects varies with the one-half power of radius, or the one-quarter power of mass, per Larson's scaling laws. The mass-to-flux ratio of these objects determines whether they have exceeded their magnetic critical mass. These objects are mapped using emission lines of (*) carbon monoxide. Isothermal contraction of “giant” examples of these objects causes them to fragment into pieces, which each collapse under their own gravity until they reach their Jeans mass. (10[1]-5[1])Ionizing a portion of these objects can form an H II (“H 2”) region. For 10 points, name these (10[1])large (-5[1])collections of gas primarily composed of (10[1])molecular hydrogen, the sites of star formation. (10[1])■END■ (0[2])

ANSWER: molecular clouds [or giant molecular clouds; prompt on GMCs; prompt on clouds or interstellar clouds or dark clouds; prompt on stellar nurseries; prompt on nebulae]
