The time evolution of the radial abundance gradients within spiral galaxies is very controversial. The gradient steepening or flattening with time are both predicted and also observed. There are only two methods to produce a radial gradient: an infall of gas variable with radius and/or a star formation rate dependent on radius. Taking into account the relationship between the production o…
This project continues the same research lines the members of the team have been working on during the last few years, aiming to describe the abundances and model the chemical evolution of galaxies, in particular the Milky Way, through the investigation of their distinct substructures. This will be done by deriving chemical abundances of photoionized nebulae and stars that can be seen as …

This project aims the determination of physical parameters and chemical abundances for a sample of extended planetary nebulae in the Galaxy. It will have three complimentary parts: data reduction and analysis of observational data will be performed for those objects already observed, new data will be collected for other targets, and these results, combined with others from the literature,…
The project intends to determine physical parameters and chemical abundances for a sample of galactic planetary nebulae with bipolar morphology, and use these results to model the objects using a photoionization code. The project has two complimentary parts: new observational data will be collected for a sample of bipolar nebulae and the results, combined to data from the literature, will…
This project proposes a comprehensive approach to describe the evolution of the central region of the Galaxy, comprising the bulge, the bar and their interfaces with the inner disk and the central region of the halo. We intend to investigate the chemical and kinematic properties of these structures, which are interconnected, aiming to separate them and apply these results to a model for t…
