Low and intermediate mass stars (0.8-8M odot) in the end of their evolution\npass through a series of events of mass loss, which contributes for the\nenrichment of the interstellar medium. The end of this evolutionary process is\npreceded by the planetary nebulae (PNe) phase, representing an important source\nof information for understanding the chemical enrichment of galaxies. The M83\nbarred galaxy is a relatively nearby galaxy, which allows the\nspectrophotometric study of its photoionized objects. In the literature, HII\nregions have been extensively explored in this galaxy, though its PNe\npopulation has not previously been addressed. In this work we report, for the\nfirst time, a spectrophotometric study of the PNe population in the M83 galaxy.\nThe data was observed with the Gemini GMOS multi-object spectrograph in 2014\nusing two grating configurations (R400 and B600) and under an excellent seeing\ncondition (< 0.8 arcsec). These data are curently being reduced with the Gemini\nPyraf package. In the first phase of this project we wish to confirm\nspectroscopically the PNe candidates of the sample to further analyze, for the\nfirst time, the radial gradient of chemical abundances from the PNe population\nin this galaxy.\n
