Recalibration of the H surface brightness-radius relation for planetary nebulae using Gaia DR3: new distances and the Milky Way oxygen radial gradient
Oscar Cavichia, Hektor Monteiro, Miguel Cerviño +3
The spatial distribution of chemical elements in the Galactic disk provides key constraints on models of galaxy evolution. However, studies using planetary nebulae (PNe) as tracers…

Analysis of the Internal Radial Gradient of Chemical Abundances in Spiral Galaxies from CALIFA
A. F. S. Cardoso, O. Cavichia, M. Mollá +1
The study of chemical evolution is of paramount importance for understanding the galaxies evolution. Models and observations propose an inside-out mechanism in the formation of spi…
