This Zenodo repository is one of three Zenodo repositories related to the article "Stellar properties of observed stars stripped in binaries in the Magellanic Clouds" by Y. Götberg, M.R. Drout, A.P. Ji, J.H. Groh, B.A. Ludwig, P.A. Crowther, N. Smith, A. de Koter, and S.E. de Mink. In the article, we analyze the optical spectra of ten stars and measure their stellar properties using spectral fitting. This repository contains observational data and the resulting measurements for the stellar properties of the stars analyzed in the article, along with best fit spectral models and spectral models used to estimate the wind mass loss rate of the stars. Below, we describe the content in more detail: 0_ReadMe.txt: A text file where we describe some more details regarding the content. S2_stacked_stellar_spectra.tar.gz (4.6 MB): The spectra we use for obtaining stellar properties for the observed stars. Table2.txt: the apparent AB magnitudes with associated errors for the stars we analyze in the paper. Table3.txt: the stellar properties for the stars we analyze in the paper. These parameters are obtained by spectral fitting. S5_spectra_best_fit_models.tar.gz (14 MB): The spectral energy distributions and normalized spectra for the best-fit models, recomputed such that the radius and bolometric luminosity also matches. This tarball contains best-fit spectra for all of the stars in text-files labeled with the format SED_StarX_xxx.txt (~70 MB when inflated). The stellar parameters are presented in Section 5. S5_full_best_fit_models.tar.gz (1.9 GB): The full CMFGEN version of the best-fit models for each individual star. This tarball contains a tarball for each star, which when inflated becomes ~250-550 MB each. S7_spectra_mdot_models (31 MB): The spectral energy distributions and normalized spectra for the models used in the mass-loss analysis that we present in Section 7. S7_full_mdot_models (3.5 GB): The full CMFGEN version of the spectral models used for the mass-loss rate variation presented in section 7 (excluding the best-fit models, which are provided separately).
