Evolution through time of the stellar wind bubble radius (orange) and velocity (blue) using the Weaver et al. (1977) (solid) and Lancaster et al. (2021a) (dashed) models, starting from the bubble’s radius and velocity at 0.23 Myr (with a corresponding density at the shell of l6.0 amu cm−3). The efficiency α parameters in the Lancaster model have both been set to 1. The dotted and dash-dotted lines denote the analytical Weaver and Lancaster solutions, respectively. The shaded regions show 25 pc and 4 km s−1, with 10% errors.
