Chevalier & Clegg Wind Model (Part 2)

For M82, measurements have been made of the parameters that determine the physical properties of the Chevalier and Clegg model (CC85). In Strickland & Heckman (2009), fitting measurements of the hot x-ray gas within the starburst region to 1D models resulted in the following parameters:

• \(\dot{M}_{hot} \approx 0.3 \times \beta_{hot} \, \mathrm{M}_{\odot} \, \mathrm{yr}^{-1}\), with \(\beta_{hot}\) in the range 1.0 - 2.8
• \(\dot{E}_{hot} \approx 6.5 \times 10^{41} \, \mathrm{erg} \, \mathrm{s}^{-1}\), with \(\epsilon\) in the range 0.3-1.0
• \(R_{*} \approx 300\) pc

Physical parameters of interest for the CC85 model with these parameters are shown in the plots below.
