Mass fluxes for O-type supergiants with metallicity Z = Z_{\sun}/5

TL;DR

This paper adapts a previous model to predict mass fluxes for O-type supergiants at the Small Magellanic Cloud's metallicity, enabling estimation of their mass-loss rates across a broad range of stellar parameters.

Contribution

It extends existing models to the SMC metallicity, providing a grid for interpolating mass-loss rates for O-type supergiants in that galaxy.

Findings

Mass flux predictions for SMC O supergiants

Interpolated mass-loss rates for a wide stellar parameter range

Potential limitations for extremely massive stars near the Eddington limit

Abstract

A code used previously to predict O-star mass fluxes as a function of metallicity is used to compute a grid of models with the metallicity of the Small Magellanic Cloud (SMC). These models allow mass-loss rates to be derived by interpolation for all O-type supergiants in the SMC, with the possible exception of extremely massive stars close to the Eddington limit.
