Limits and epistemological barriers to the human knowledge of the natural world
J. E. Horvath, R. R. Fernandes, T. P. Idiart
The goal of this article is to give an overview of the current limitations and epistemological barriers in Science and Scientific Philosophy from a very general point of view. We f…
On the ontological ambiguity of Physics facing Reality
J. E. Horvath, R. Rosas Fernandes, T. E. Idiart
We discuss in this work the contradictory position in modern Physics between the existence of a microphysical quantum Reality and macrophysical classical one. After discussing some…
Nucleosynthesis and chemical evolution of intermediate-mass stars: results from planetary nebulae
W. J. Maciel, R. D. D. Costa, T. E. P. Idiart
Planetary nebulae (PN) are an excellent laboratory to investigate the nucleosynthesis and chemical evolution of intermediate mass stars. In these objects accurate abundances can be…
Age distribution of the central stars of galactic disk planetary nebulae
W. J. Maciel, R. D. D. Costa, T. E. P. Idiart
The determination of ages of central stars of planetary nebulae (CSPN) is a complex problem, and there is presently no single method that can be generally applied. We have develope…
Planetary nebulae and the chemical evolution of the Magellanic Clouds
W. J. Maciel, R. D. D. Costa, T. E. P. Idiart
The determination of accurate chemical abundances of planetary nebulae (PN) in different galaxies allows us to obtain important constraints of chemical evolution models for these s…
Chemical evolution of the Magellanic Clouds based on planetary nebulae
W. J. Maciel, R. D. D. Costa, T. E. P. Idiart
Planetary nebulae (PN) are an essential tool in the study of the chemical evolution of the Milky Way and galaxies of the Local Group, particularly the Magellanic Clouds. In this wo…
