Dynamics of Biased Domain Walls and the Devaluation Mechanism
P. P. Avelino, C. J. A. P. Martins, L. Sousa
We study the evolution of biased domain walls in the early universe. We explicitly discuss the roles played by the surface tension and volume pressure in the evolution of the walls…
On the cosmological evolution of alpha and mu and the dynamics of dark energy
P. P. Avelino
We study the cosmological evolution of the fine structure constant, , and the proton-to-electron mass ratio, , in the context of a generic class of models where the g…
Estimation of stellar parameters using Monte Carlo Markov Chains
M. Bazot, S. Bourguignon, J. Christensen-Dalsgaard
We apply Monte Carlo Markov Chain methods to the stellar parameter estimation problem. This technique is useful when dealing with non-linear models and allows to derive realistic e…
Clustering Properties of Dynamical Dark Energy Models
P. P. Avelino, L. M. G. Beca, C. J. A. P. Martins
We provide a generic but physically clear discussion of the clustering properties of dark energy models. We explicitly show that in quintessence-type models the dark energy fluctua…
Current Issues in Asteroseismology
Michael Bazot, Mario J. P. F. G. Monteiro, Christian W. Straka
In this contribution we briefly review some of the current issues and promises for the future by asteroseismology. We are entering a new phase in this field driven by the wealth of…
Inter-comparison of the g-, f- and p-modes calculated using different oscillation codes for a given stellar model
A. Moya, J. Christensen-Dalsgaard, S. Charpinet +9
In order to make astroseismology a powerful tool to explore stellar interiors, different numerical codes should give the same oscillation frequencies for the same input physics. Th…
