Thermodynamical and dynamical equilibrium of a self-gravitating uncharged thin shell
Santiago Esteban Perez Bergliaffa, Marcelo Chiapparini, Luz Marina Reyes
The dynamical stability of massive thin shells with a given equation of state (EOS) is here compared (both for the barotropic and non-barotropic case) with the results coming from…
A Nuclear Structure Model for Double Charge-Exchange Processes
V. dos S. Ferreira, A. R. Samana, F. Krmpotić +1
A new model, based on the BCS approach, is specially designed to describe nuclear phenomena of double-charge exchange (DCE). After being proposed, and…
An introductory study to white dwarfs
Sílvia Pereira Nunes, Marcelo Chiapparini, Santiago Esteban Perez Bergliaffa
White dwarfs are compact objects that stand against gravitational collapse by their internal pressure of degenerate matter. In this work we aimed to perform an introductory study o…
A QCD sum rules calculation of the strong coupling constant
B. Osório Rodrigues, M. E. Bracco, M. Chiapparini +1
In this work, we calculate the form factors and the coupling constant of the strange-charmed vertex in the framework of the QCD sum rules by studying their three-poi…
Gravitational wave generation from dynamical shape transition of protoneutron stars
Hilario Rodrigues, Ana Maria Endler, Sergio B. Duarte +1
We describe the dynamical behavior of newborn pulsars modeled as homogeneous rotating spheroids. The dynamical evolution is triggered by the escape of trapped neutrinos, provided t…
The strong coupling constant from QCD Sum Rules
Bruno Osório Rodrigues, Mirian Enriqueta Bracco, Marcelo Chiapparini
The coupling constant of the meson vertex is calculated using the three point correlation function within the QCD Sum Rule formalism. We have considered alternately me…
