# Chevalier & Clegg Wind Model (Part 2)

## January 20, 2016

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.
