Abstract [en]

We present a re-analysis of spectroscopic data for 23 H(II) regions in 12 blue, metal-poor, low surface brightness galaxies (LSBGs), taking advantage of recent developments in calibrating strong-line methods. In doing so, we have identified a galaxy (ESO 546-G34) which may be the most-metal-poor LSBG found in the local Universe. Furthermore, we find evidence that blue, metal-poor LSBGs, together with blue compact galaxies (BCGs) and many other HII galaxies, fall outside the regular luminosity-metallicity relation. This suggests that there might be an evolutionary connection between LSBGs and BCGs. In such cases, several very metal poor LSBGs should exist in the local Universe.
