DESCRIPTION:Speakers: Mahdieh Navabi (The University of Surrey)\nThe Small
  Magellanic Cloud (SMC)\, as one of the nearest galaxies to us\, provides 
 a superb laboratory for studying its stellar populations in exquisite deta
 il.  We collected the largest sample of SMC red giant branch (RGB) stars (
 ~6000) observed using the AAOmega spectrograph fed by the Two Degree Field
  (2dF) multi-object system at the Anglo-Australian Telescope of the Siding
  Spring Observatory (Australia).  The metallicities were recovered using a
  direct estimation of [Fe/H] from the equivalent widths of the Calcium tri
 plet (CaT). We discuss the potential implications of the metallicity gradi
 ents and compare these to previous determinations of star formation histor
 ies to assess the consequences of encounters between the SMC and Large Mag
 ellanic Cloud.\n **Finally\, we discuss our findings in the context of the
  correlation that exists between metallicity and dynamical mass in dwarf I
 rregular systems\, of which the SMC is our closest example.**\n\nhttps://i
