Description
Stellar winds are mechanisms through which stars lose mass from their outer layers. Although the underlying physical processes are not yet fully understood, stellar winds can strongly influence stellar evolution and determine the final fate of a star. In this work, we investigate stripped helium stars, i.e., stars that have lost their hydrogen-rich envelopes due to binary interaction. Our aim is to explore how different assumptions for the wind strength affect their subsequent evolution. Current prescriptions are largely extrapolated from Wolf-Rayet stars, which are hotter and more luminous, while recent observations suggest that stripped stars may have weaker winds than previously expected. Using stellar evolution simulations, we find that varying the wind strength can lead to different types of core-collapse supernova progenitors, ranging from compact hot blue stars to extended yellowish supergiants.
