Spatial and observational homogeneities of the galaxy distribution in standard cosmologies
L. J. Rangel Lemos, Marcelo B. Ribeiro
This work discusses the possible empirical verification of the geometrical concept of homogeneity of the standard relativistic cosmology considering its various definitions of dist…
On the common origin of the AB Dor moving group and the Pleiades cluster
V. G. Ortega, E. Jilinski, R. de la Reza +1
AB Dor is the nearest identified moving group. As with other such groups, the age is important for understanding of several key questions. It is important, for example, in establis…
Abundances of Mn, Co and Eu in a sample of 20 F-G disk stars: the influence of hyperfine structure splitting
E. F. del Peloso, K. Cunha, L. da Silva +1
We present Mn, Co and Eu abundances for a sample of 20 disk F and G dwarfs and subgiants with metallicities in the range -0.8 <= [Fe/H] <= +0.3. We investigate the influence of hyp…
The age of the Galactic thin disk from Th/Eu nucleocosmochronology III. Extended sample
E. F. del Peloso, L. da Silva, G. F. Porto de Mello +1
The first determination of the age of the Galactic thin disk from Th/Eu nucleocosmochronology was accomplished by us in Papers I and II. The present work aimed at reducing the age…
The age of the Galactic thin disk from Th/Eu nucleocosmochronology II. Chronological analysis
E. F. del Peloso, L. da Silva, L. I. Arany-Prado
The purpose of this work is to resume investigation of Galactic thin disk dating using nucleocosmochronology with Th/Eu stellar abundance ratios, a theme absent from the literature…
The age of the Galactic thin disk from Th/Eu nucleocosmochronology I. Determination of [Th/Eu] abundance ratios
E. F. del Peloso, L. da Silva, G. F. Porto de Mello
The purpose of this work is to resume investigation of Galactic thin disk dating using nucleocosmochronology with Th/Eu stellar abundance ratios, a theme absent from the literature…
