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://m eetings.aip.de/event/20/contributions/275/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/20/contributions/275/ END:VEVENT END:VCALENDAR
