Description

This zenodo repository provides supplementary material linked to the article "Binarity at LOw Metallicity (BLOeM): Pipeline-Derived Physical Properties of OB stars" by J.M. Bestenlehner, P.A. Crowther, V. Bronner et al. (MNRAS accepted). The article involves spectral analysis of 778 OB stars in the Small Magellanic Cloud (SMC), with VLT/FLAMES observations drawn from the BLOeM survey (see Shenar et al. 2024 A&A 690, A289 10.1051/0004-6361/202451586 ) and the pipeline is described in Bestenlehner et al. 2024 MNRAS 527, 9023 https://doi.org/10.1093/mnras/stae298

The content included is as follows:

BLOeM_fits_24nov2024_run2_lineIDs.pdf

Normalized theoretical optical spectra (shown in red) superimposed upon spectroscopic observations of 778 SMC stars (shown in blue), in PDF format. Spectroscopic observations are the initial 9 epochs from VLT/FLAMES cross-correlated and combined after correction for individual radial velocities.
