Stellar Winds in Cluster Cores
Volume-rendered images of a hydrodynamical simulation I constructed using FLASH, a high-performance application code, and yt are illustrated here. This simulation traces the interacting stellar winds of 50 evolved stars within the core of a stellar cluster. The colors reveal density differences in the environment. I also track the wind temperature and the ionization state of these interacting outflows. The winds permeate outward, shocking as they collide. Hot, tenuous stellar winds are observed to escape the core in thin filaments, while very few stars contribute to mass accumulation in the cluster. The intracluster densities produced are in agreement with observational measurements.
