Mass–metallicity relation for the H IX galaxies: we show the gas-phase metallicity (determined with the O 3N 2 parameter following Pettini & Pagel 2004) as a function of stellar mass. The contours enclose 64 and 90% of SDSS galaxies. The circle indicates the CONTROL galaxy IC 4857 and H IX galaxies are marked with stars. All symbols are also colour-coded by the H I mass fraction.
