Stellar winds are ubiquitous among stars, but become increasingly important for high-mass stars.
Along with binary interactions, they are a prominent mechanism for producing Wolf-Rayet stars.
What's more important: binary interactions or stellar winds?
I use multiwavelength data (UV-VIS-IR) and sophisticated model atmospheres to determine the structure and impact of stellar winds to answer this and other related questions.
