Notes. The definitions of each symbol can be found in Table 1 in Krumholz et al. (2018). The momentum injection rate used is based on simulations (e.g. Hayward & Hopkins 2017; Krumholz et al. 2018, and references therein) and assumes that supernova remnants undergo an energy-conserving (Sedov-Taylor) phase (Sedov 1946, 1959; Taylor 1950), where energy is converted into momentum. However, this value can vary by up to a factor of 4, which could sustain a higher velocity dispersion of the critical value ∼ 20 km s⁻¹. To match the properties of CRISTAL disks using star-formation feedback alone, a factor of 10 larger than this adopted value would be required.
