This BCD is one of the two lowest-metallicity galaxies where LBV stars were detected, allowing us to study the LBV phenomenon in the extremely low metallicity regime. We determine abundances of nitrogen, oxygen, neon, sulfur, argon, and iron by analyzing the fluxes of narrow components of the emission lines using empirical methods and study the properties of the LBV from the fluxes and widths of broad emission lines. Description: Fig1.dat - the flux-calibrated and redshift-corrected VLT/X-shooter UV and optical spectrum of the low-metallicity blue compact dwarf galaxy PHL 293B. Fig2.dat - the flux-calibrated and redshift-corrected VLT/X-shooter near-infrared spectrum of the low-metallicity blue compact dwarf galaxy PHL 293B.
