| Abstract: | The main outer ring of the WR nebula NGC 2539 expands radially with velocity  26kms–1. The dynamics are modelled as the interaction of the winds from the O progenitor and the present WR stage with clumpy molecular cloud material and Red Supergiant ejecta. In both stages, the bubbles are driven by wind momentum. The necessary radiative energy loss probably occurs in boundary layers between cool clumps and hot shocked wind. |
