Abstract

Massive stars shape the surrounding ISM by emitting ionizing photons and ejecting material through stellar winds. We study the impact of the transfer of momentum from the wind of a massive star on the surrounding neutral or ionized material. We use the Smoothed Particle Hydrodynamics (SPH) code SEREN [3] including a newly implemented HEALPix-based momentum conserving wind scheme. The transfer of momentum from a wind onto the cold surrounding gas drives the expansion of a shock front, sweeping up the neutral material into a dense shell. In contrast, we find the momentum driven wind to have only little direct effect on the warm ionized gas.
