摘要

Metallicity gradients are important constraints for models of chemical evolution of the Galaxy. We present the current radial gradient of oxygen abundances using a sample of main -sequence OB stars located in the outer Galactic Disk, considering non-NLTE abundances, and distances based on GAIA DR2 results. We compare the obtained gradient with results from other young objects of the Galactic Disk.
