SUMMARY:A fundamental relation between the metallicity\, gas content\, and
  stellar mass of local galaxies - Matt Bothwell (Cavendish/KICC)

DESCRIPTION:Recent results have suggested that the well known mass-metalli
 city relation\nhas a strong dependence on the star formation rate\, to the
  extent that a\nthree dimensional fundamental metallicity relation exists 
 which links the\nthree parameters with minimal scatter. In this talk\, I d
 escribe work using a\nlarge sample of local galaxies observed in atomic hy
 drogen from the ALFALFA\nsurvey to demonstrate\, for the first time\, that
  a similar fundamental\nrelation (the HI-FMR) also exists between stellar 
 mass\, gas-phase\nmetallicity\, and HI mass. This latter relation is likel
 y more fundamental\,\ndriving the relation between metallicity\, SFR and m
 ass.\n
