Density (top) and temperature (bottom) structure of the MESA (gray) and CMFGEN (colored) models of a stripped star and its atmosphere. We show our reference model (Z = 0.0166). The different colors of the CMFGEN models correspond to the standard, reduced and enhanced wind mass loss rates. The inset provides a zoom-in, which shows that the connection is not perfect. However, as shown by the horizontal arrow, the mismatch in the radial direction is very small and translates to an error in the surface temperature that is much less than 1% (see main text), which is more than sufficient for the purposes of our study.
